War zone drone crashes add up
Thirty-eight Predator and Reaper drones have crashed during combat missions in Afghanistan and Iraq, and nine more during training on bases in the U.S. — with each crash costing between $3.7 million and $5 million. Altogether, the Air Force says there have been 79 drone accidents costing at least $1 million each.
NRao ji , US is not giving Predators or Reapers to Pakistan at least till now.They have offered Pakistan only Shadow UAVs till now which are tactical UAVs.

Secondly UAVs are used much more than manned aircrafts in terms of hours.Also since they are unmanned maybe the maintenance is not that intensive(this is purely my speculation).In fact that's what the article states that certain design and software problems were never rectified.Hence the no. of crashes are also more.Other than that these UAVs are top notch UAVs with tremendous capabilities.Let's hope they are never given to Pakistan.

we rarely see this in India. USN seems be firing right and left. below is over period of 2 months only. and these are not deck
hands but commanders of big ships.

Navy has fired 6 commanders since January, triple its usual monthly rate

By Craig Whitlock
Washington Post Staff Writer
Saturday, March 6, 2010

The Navy has fired six commanding officers since the start of the year -- triple its usual monthly rate -- including a foul-mouthed captain who was dismissed for subjecting her crew to "cruelty and maltreatment" aboard a warship in the Pacific.

Capt. Holly Graf, commander of the USS Cowpens, a guided-missile cruiser, was relieved of duty Jan. 13 after an investigation found she cursed so much at her 400-member crew that even the sailors -- no strangers to four-letter words -- were intimidated.

According to the Navy inspector general's report released this week, officers complained that their captain humiliated them in front of the rest of the crew by calling them "idiots" and "stupid" as she spat a stream of obscenities. One noncommissioned officer said Graf treated him like a toddler, forcing him to take a "time out" by standing alone in an empty watch room.
:eek:

Although verbal abuse would hardly put Graf among the worst tyrants ever to command a ship at sea, her former crew members have been exacting mutinous revenge in recent weeks by posting hundreds of anonymous comments on the Internet that describe her as "Horrible Holly," as well as a modern-day Captain Bligh.

Graf's has been highlighted in much of the criticism. One Web site, http://www.militarycorruption.com, called her "an incompetent and unstable 'politically correct' poster girl for all the super feminists at the Pentagon and the U.S. Naval Academy."

Graf has also been accused on the Web site of endangering sailors' lives by engaging the Cowpens in a "drag race" with a destroyer, the USS John S. McCain, near Okinawa, Japan. The inspector general's report confirmed that the race had taken place last year but concluded that allegations Graf had endangered the Cowpens were "unsubstantiated."

The six commanding officers the Navy has fired since Jan. 8 represent an unusually high number for the service. A total of 55 commanding officers were dismissed for cause from 2005 to 2009, an average of 11 a year, according to statistics supplied by the Navy.

Lt. Justin Cole, a Navy spokesman, said that fewer than 1 percent of the service's approximately 1,500 commanding officers are relieved each year but added that the spate of firings so far in 2010 was not part of a planned crackdown or policy change.

"We hold them to high standards," he said of the officers. "But standards of accountability have remained consistent throughout the years."

Many Navy skippers who get the boot have been accused of sexual misbehavior. One commanding officer was fired in January after he was arrested on charges of soliciting oral sex from an undercover officer for $20. Another commander was dismissed last month for being involved in "an inappropriate relationship" with a female officer, according to the Navy.

Navy culture and standards dictate that a captain is held responsible for any major mishap on a ship; a commander will almost certainly be fired, for instance, if a vessel runs aground, even if low-ranking sailors were directly to blame.

A study conducted last year by the Navy Times, however, found that personal misconduct was the leading cause of commanders losing their jobs, with about one-third of all firings occurring for that reason between 1999 and 2008.

Findings of "cruelty and maltreatment" -- the judgment levied against Graf -- are few and far between.

The Naval Inspector General's office launched its investigation of Graf in June after receiving three anonymous complaints. Of the 36 sailors who were subsequently interviewed, 29 said she had verbally abused them, according to the 50-page report. Crew members cited an "environment of fear and hostility" on the Cowpens, with one saying, "21 years in the Navy and this is the poorest climate I've ever seen."

Investigators upheld other allegations against Graf, including that she abused her position for personal gain by forcing sailors to walk her dogs and by compelling a junior officer to play piano at a Christmas party at her house.

Graf took command of the Cowpens, based in Yokosuka, Japan, in March 2008. Navy officials said she had declined all interview requests since being relieved of command. She did not respond to an e-mail seeking comment for this article.

In a written response to Navy investigators, she acknowledged resorting to foul language, but justified it as a tactic for getting crew members' attention.

"Many times I raised my tone (and used swear words) to ensure they knew this time, it was no kidding," she wrote. "I also did it on other occasions to intentionally pressurize the situation."

Navy officials said Friday that Graf has remained at Yokosuka Naval Base since she was fired, pending reassignment to the Navy Air and Missile Defense Command in Dahlgren, Va.

Air Force Aims to Launch 'Spy Pigeon' Drone by 2015
Image
(July 08) -- In the run-up to the invasion of Iraq, U.S. officials often had to rely on grainy satellite photos to decide whether facilities on the ground were intended for producing weapons of mass destruction. Now imagine that instead of overhead satellite imagery -- or even high-flying unmanned aircraft -- they could send in a flock of microdrones that could actually fly right over, or even inside, such facilities.

Even better, these drones -- equipped with chemical sensors that could pick up possible weapons work with near certainty -- would resemble typical birds, like pigeons, making them nearly impossible to spot.

This high-tech spy vision is precisely what Air Force researchers are trying to build, and they believe such a microdrone is not only possible, but could be ready to fly in just five years.

"Ideally, it'll be a bird-sized UAV [unmanned aerial vehicle], with the current goal being a pigeon," Dr. Leslie Perkins, the lead for micro air vehicles at the Air Force Research Laboratory, told AOL News. The "birdlike" UAV would also be able to operate with minimal pilot intervention for up to a week at a time, she said.

The scenario that the Air Force envisions for its would-be spy pigeon is a cross between the high-tech military thrillers of Tom Clancy and the science-fiction novels of Isaac Asimov. It would fly with almost no human interaction and be equipped with advanced sensors capable of detecting nuclear, biological or chemical weapons.

To date, the prototype hasn't progressed much beyond the world of RadioShack, which sells a variety of animal-inspired toy planes, such as a flying bat. The Air Force Research Lab recently displayed a prototype of its bird, built by Ohio-based Theiss Aviation, at a trade show in Florida.

Though the bird is supposed to eventually have flapping wings, the current model has fixed wings with a push propeller in back; it has flown for about half an hour in a test facility.

Air Force researchers hope that in a few years, however, the bird will look and fly like a real pigeon -- and even perch inconspicuously on power lines to recharge. While there are a number of universities and companies working on micro air vehicles, the Air Force Research Lab has laid out a specific goal to field a bird-inspired drone by 2015, and then one based on an insect by 2030.

As part of its research, the Air Force Research Lab in May officially opened a $1.5 million testing facility, called the micro-aviary, dedicated specifically for micro air vehicles. Perkins, who helps coordinate researchers' work across the lab's various locations, says everyone knows that they are pushing the envelope on technology.

Among the challenges faced with micro air vehicles, for example, is finding a power source that is small yet powerful enough to provide the drones with endurance. Though a number of private companies build micro air vehicles, like AeroVironment's WASP drone, they can typically only fly for less than an hour.

The Air Force Research Lab, by comparison, wants its micro air vehicle to operate for a week at a stretch. "When you talk with private firms, they don't necessarily laugh, but they do realize that's a holy grail," Perkins said.

The pigeon drone builds on a growing interest in biomimetics, which draws on nature to inspire technology. In the case of robots and drones, this means studying everything from spiders to hummingbirds to understand how they move.

Well, it will actually be unfair to blame Bolden Jr. as clearly he is just a medium for advancing his "Boss' " agenda..
surely, The Obama Administration has gone way out of it's league in its over zealous efforts to be seen as a more acceptable regime amongst the Islamic world..

AgustaWestland and Thales Unveil Enhanced Airborne Surveillance and Control Capability
Image Image
AgustaWestland, a Finmeccanica company, and Thales unveiled an enhanced Airborne Surveillance and Control (ASaC) capability, at RNAS Yeovilton on 10th July during the Fleet Air Arm’s annual Air Day. The low cost, low risk capability builds upon the combat proven Sea King Mk7 ASaC Cerberus mission system and Searchwater 2000 radar, to provide enhanced operational effectiveness through the use of the next generation AgustaWestland AW101 helicopter. AgustaWestland and Thales have teamed to jointly explore the potential for this capability in advance of the keenly expected MoD requirement to replace the Sea King Mk7 ASaC aircraft after its planned retirement in 2016.
Nick Whitney, Senior VP UK Government Business Unit, AgustaWestland said “The AgustaWestland solution will deliver an enhanced, cost effective and low risk capability which exemplifies the role of an ASaC capability fit for the 21st century. The solution we have developed capitalises on the substantial investment already made by the MoD in both the helicopter and the excellent Thales Cerberus mission system and radar.” Ed Lowe, Chief Operating Officer of Thales UK said, “Sea King Mk 7 is a highly successful ASaC platform which has proved itself over land and sea. Thales looks forward to working with AgustaWestland to develop a proposal to transfer our Cerberus mission system to the AW101 platform. I am confident this will offer our customer a low cost, low risk method of delivering ASaC well into the future with no capability gap”.
The palletised Searchwater 2000 radar is deployed through the rear ramp aperture when in operation and stows in the cabin when not in use, enabling rapid transit between tasking. Two aft-facing modernised mission crew stations are located at the forward end of the cabin. The following key features and benefits are also included:

• Long range, look up/look down air, land and sea capability
• Human Machine Interface optimised for two man operation
• Fully integrated Link 16 Command and Control capability
• Modern platform extends 360 deg radar horizon and significantly increases mission range and endurance

The palletised ASaC equipment also enables a front line re-role capability delivering greater aircraft utility. The ASaC equipment could be role fitted to all AW101 utility variants.

Sweden Will Buy New Gripen
One question for Saab’s Gripen Next Generation (NG) project has always been: Why should export customers buy an aircraft when its home customer has not committed to it? In discussions in June at Saab’s Linkoping, Sweden, headquarters, it became apparent that the NG is firmly in national defense plans, but a formal announcement is being delayed for domestic reasons.

Sweden has committed to using the Gripen beyond 2040,” says Hans Rosen, head of Gripen marketing and campaigns. “The question is when to acquire the Gripen NG, and how many.” The program calls for the new variant to enter Swedish service around 2018, but Sweden has told export customers—some of which expect deliveries in 2014—that it will adjust its schedule so Sweden deploys the NG before they do.

Rosen’s comments on the future of the Gripen in Sweden echoed remarks made by Defense Minister Sten Tolgfors at an air power conference at Malmen in June. Tolgfors said modernization of the Gripen force is proceeding according to plan with conversion of a final batch of 31 JAS 39A models to the 39C standard.

This leaves the air force with 100 fighters, fewer than at any time during or since the Cold War. Sweden will offset the reduction by maintaining the force at a high technical standard. The next step will see all JAS 39C/D fighters modernized to a common configuration known as Materiel Standard (MS) 20, already under contract. Also approved is the integration of a new radar-guided missile, the MBDA Meteor, regarded by Saab as a massive improvement in lethality over the AIM-120C advanced medium-range air-to-air missile.

The next configuration, MS 21, is being defined, but it is clear that MS 21 is in fact the NG, with the General Electric F414G engine; modified airframe; Selex Galileo Raven ES-05 active, electronically scanned array (AESA) radar; Skyward-G infrared search and track (IRST) system; and new core avionics. Selex’s Raven 1000P radar prototype is flying on the Gripen Demo and a ground rig is testing the innovative avionics in which flight-critical functions are partitioned so mission capabilities can be added more quickly through the fighter’s life.

The government is funding development of the definitive NG, which the independent defense procurement agency FMV calls JAS 39E/F. (A contract for the avionics system was issued in May.) The production version will have a larger wingspan and area, and the landing gear will be fully integrated with the wing (on the Demo, gear loads are taken through the wing and fuselage). Maximum takeoff weight has been increased (compared with earlier NG proposals) by 1,100 lb. to 36,400 lb.

The upgrade to the new airframe is logical for the Swedish air force. Putting the heavier AESA, plus Meteor and IRST on the C/D would reduce range and speed. However, the smaller fighter force means there are only three fighter bases, each covering a larger area. Since air defense is a primary mission, the air force wants longer reach in its fighters. JAS 39E/F provides that not only through greater range, but with supercruise—sustained Mach 1.2+ on military power with an air-to-air weapons load—that allows the fighter to reach a threat more quickly and with higher energy. Raven, Skyward-G and 4-8 Meteor air-to-air missiles also allow a threat to be identified and engaged at greater range.

Saab takes a long view of the Gripen program, Rosen says, and is confident of continued Swedish support and further export sales regardless of the outcome of competitions in Brazil, India and Switzerland. Although many regard Gripen as an outsider in the fighter business, it has won more export competitions than Rafale, Typhoon or Super Hornet.

The Demo prototype completed 152 flight-test sorties by mid-June, Rosen said, and a successful demonstration in India in May (the company previously performed demonstrations with the C/D version in India), including a landing and engine restart at Leh airfield in Kashmir, 10,800 ft. above sea level.

Nano-enabled Coating Makes Aircraft Invisible

The Israel-based Ynetnews is reporting that an Israeli company called Nanoflight has successfully run a test on dummy missiles that were painted with the nano-enabled coating and have shown that radar could not pick them up as missiles.
The YnetNews article rather brutally points out that painting an aircraft with this nanocoating is far cheaper than buying a $5 billion US-made stealth aircraft. Of course, it should also be noted that one sale of a $5 billion aircraft employs a large number of aeronautical engineers, and the high price tag also makes it far more difficult for others to purchase the technology and possess the ability to sneak up on an enemy as well.
The nanocoating achieves its radar trickery by absorbing the radio waves emitted by the radar and scattering them as heat energy enough so that when the radar gets the bounced back signal it is not regular enough to indicate an object.
It seems that nano-enabled paint is the way towards commercial success in nanotechnology as I discovered at London conference a couple of years ago in which a number of projects producing exotic nanomaterials were trotted out but only one company that actually made a nano-enabled product: a paint.
Nanoflight appears pretty far along in its development process as well. A spokesman for Nanoflight, Eli Shaldag, is quoted in the article indicating that the company is in the second stage of its development process after which they will be able to produce the coating in larger quantities.
The company also sees an opportunity to use the material on the soldiers to make them invisible to infrared and night-vision goggles.

Flight Demonstrations of MQ-8B Fire Scout VUAS in United Arab Emirates
Image
With the support of the United States Navy, Northrop Grumman Corporation and its industry partners (Sikorsky/Schweizer, Rolls-Royce, Raytheon, FLIR Systems, Cubic, Kearfott, Rockwell-Collins, General Electric, Sierra Nevada, Telephonics, and L-3 Communications) today successfully completed a rigorous set of flight demonstrations of the MQ-8B Fire Scout vertical unmanned aerial system (VUAS) in the United Arab Emirates under extreme environmental conditions.

The test flights were conducted in early July over a ten day period in the United Arab Emirates. They validated Fire Scout's steady system maturation and helped signal its readiness for the U.S. Navy's upcoming Operational Evaluation of the system, planned for late 2010 aboard the USS Halyburton (FFG-40).

"We welcome Northrop Grumman and the U.S. Navy to the UAE for continued testing of the Fire Scout," said Ali Al Yafei of ADASI (Abu Dhabi Autonomous Systems Investment). "As a VUAS, Fire Scout has many unique capabilities to offer and we're looking forward to reviewing the results of this in-country testing."

The Fire Scout demonstrations included numerous takeoffs and landings in hot, windy and sandy conditions in temperatures as high as 47 degrees Celsius (117 degrees Fahrenheit). The VUAS also conducted various test flights at altitudes up to 3,000 meters (9,842 feet) . These demonstration missions included non-line-of-sight operations that showcased Fire Scout's ability to operate autonomously in remote locations, and its FLIR Systems electro-optical/infrared (EO/IR) sensing capabilities used to locate and acquire targets.

Video imagery from the testing was presented today at a post-testing event to an audience of interested multi-national government agencies, and domestic and international media. The imagery, a compilation of video produced by Fire Scout's sensors during field trials, demonstrated the VUAS's real-time imagery-transmission capability, a vital element of the intelligence, surveillance and reconnaissance missions it performs for military forces

Europe studies new rocket options(BBC)
The director general of Esa, Jean-Jacques Dordain, said recently that Europe needed to "reflect on", and "learn lessons" from, the maiden launch of the US Falcon 9 rocket developed by the SpaceX company.

The total development costs of the Falcon 9 to its first flight in June were about half a billion dollars, SpaceX CEO Elon Musk has claimed.

The California company is currently advertising launch prices that dramatically undercut those of its competitors, including Arianespace, the firm which markets the Ariane 5.

Very unlikely, true, but isn't the MTCR only limited to "missile Technology" ? A UCAV or UAV would not typically fall under that classification of the treaty. Or does it ? Also, is the British UCAV capable of carrying nukes or other WMD because I don't think they have stated as much and if it is capable or intended to do so, it would be another matter altogether.

No, MTCR applies to UCAV's as well.....
From MTCR website : http://www.mtcr.info/english/guidelines.html
Greatest restraint is applied to what are known as Category I items. These items include complete rocket systems (including ballistic missiles, space launch vehicles and sounding rockets) and unmanned air vehicle systems (including cruise missiles systems, target and reconnaissance drones) with capabilities exceeding a 300km/500kg range/payload threshold; production facilities for such systems; and major sub-systems including rocket stages, re-entry vehicles, rocket engines, guidance systems and warhead mechanisms.

The remainder of the annex is regarded as Category II, which includes complete rocket systems (including ballistic missiles systems, space launch vehicles and sounding rockets) and unmanned air vehicles (including cruise missile systems, target drones, and reconnaissance drones) not covered in item I, capable of a maximum range equal to or greater than, 300km. Also included are a wide range of equipment, material, and technologies, most of which have uses other than for missiles capable of delivering WMD. While still agreeing to exercise restraint, partners have greater flexibility in the treatment of Category II transfer applications.

Then how come BrahMos isn't a violation of MTCR?
I always thought it wasn't covered because it's a cruise missile.

And doesn't MTCR restrict not just development but also sale of relevant items?
How is Pak able to openly demand that the US provide it with drones?

In that case there is no difference... the range & payload limits are the same....The only difference is the speed & that is irrelevant in case of MTCR

Su-35 Is Sukhoi’s Main Short-term Export Hope
(AINOnline reports)
While development of the T-50 PAK-FA gathers pace, the Su-35 remains Sukhoi’s export priority for the next five to seven years. The aircraft is designed to plug the gap between the existing Su-30 and future fifth-generation fighters. According to Sukhoi, the Su-35 already incorporates some fifth-generation technology, thereby having an edge over other fourth-generation combat platforms.

The Su-35 is powered by NPO-Saturn 117S engines that have had their thrust increased by 16 percent with a new fan, and high- and low-pressure turbines. They also feature Fadec controls and a thrust vector control nozzle. They promise twice the service life of the Sukhoi fighter’s earlier AL-31F engines, and the Su-35 airframe boasts an extended service life of up to 6,000 flight hours, which should give it an operational life spanning 30 years.

Innovation in the Su-35 avionics suite is built around a cockpit management system with a pair of 15-inch color, multifunction displays, a multifunction console with an integrated display processor, a 20- by 30-degree head-up display and a control panel. At the heart of the fighter’s fire control system is the new Irbis-E phased array radar with improved target acquisition range.

The Su-35 has completed its flight trials and during the second half of this year the first series production aircraft is due to leave the Sukhoi factory in Komsomolsk as part of a five-year contract from Russia’s defense ministry. Initial export deliveries are due to begin in 2012

I just assumed that if it's hypersonic, it's going to be traveling a lot more than 300 miles.
That is every jingo's dream sir :(

With Brahmos Hypersonic it will make its time to target shorter and lethality increased many fold , it wont make its range longer then restricted by MTCR.

SEOUL — South Korea has developed a longer-range cruise missile capable of hitting nuclear or military sites in North Korea, a report said Saturday.

The state-run Agency for Defense Development has begun manufacturing the ground-to-ground Hyunmu-3C with a range of up to 1,500 kilometres (937 miles), Yonhap news agency quoted an unidentified defence official as saying.

The Hyunmu-3C missile would also be able to reach parts of China, Japan and Russia. The previous version of the Hyunmu had a range of only 1,000 km.

The Secret History of Silicon Valley Part 15: Agena – The Secret Space Truck, Ferret’s and Stanford
Lockheed Agena

Thor/AgenaD w/Corona
In addition to the CORONA CIA reconnaissance satellites, Lockheed was building another assembly line, this one for the Agena – a space truck. The Agena sat on top of a booster rocket (first the Thor, then the Altas and finally the Titan) and had its own rocket engine that would help haul the secret satellites into space. The engine (made by Bell Aerosystems) used storable hypergolic propellants so it could be restarted in space to change the satellite’s orbit. Unlike other second stage rockets, once in orbit, the CORONA reconnaissance satellite would stay attached to the Agena which stabilized the satellite, pointed it in the right location, and oriented it in the right direction to send its recovery capsule on its way back to earth.
The Agena would be the companion to almost all U.S. intelligence satellites for the next decade. Three different models were built and for over a decade nearly four hundred of them (at the rate of three a month) would be produced on an assembly line in Sunnyvale, and tested in Lockheed’s missile test base in the Santa Cruz mountains.
Agena Ferrets – Program 11
As Lockheed engineers gained experience with the Agena and the CORONA photo reconnaissance satellite, they realized that they had room on a rack in the back of the Agena to carry another payload (as well as the extra thrust to lift it into space.) By the summer of 1962, Lockheed proposed a smaller satellite that could be deployed from the rear of the Agena. This subsatellite was called Program 11, or P-11 for short. The P-11 subsatellite weighed up to 350lbs, had its own solid rockets to boost it into different orbits, solar arrays for power and was stabilized by either deploying long booms or by spinning 60-80 times a second.

Agena Internals
And they had a customer who couldn’t wait to use the space. While the CORONA reconnaissance satellites were designed to take photographs from space, putting a radar receiver on a satellite would be enable it to receive, record and locate Soviet radars deep
inside the Soviet Union. For the first time, the National Security Agency (working through the National Reconnaissance Office) and the U.S. Air Force could locate radars which would threaten our manned bombers as well as those that might be part of an anti-ballistic missile system. Most people thought the idea was crazy. How could you pick up a signal so faint while the satellite was moving so rapidly? Could you sort out one radar signal from all the other noise? There was one way to find out. Build the instruments and have them piggyback on the Agena/CORONA photo reconnaissance satellites.
But who could quickly build these satellites to test this idea?
Stanford and Ferrets
Just across the freeway from Lockheed’s secret CORONA assembly plant in Palo Alto, James de Broekert was at Stanford Applied Electronics Laboratory. This was the Lab founded by Fred Terman from his WWII work in Electronic Warfare.
“This was an exciting opportunity for us,” de Broekert remembered. “Instead of flying at 10,000 or 30,000 feet, we could be up at 100 to 300 miles and have a larger field of view and cover much greater geographical area more rapidly. The challenges were establishing geolocation and intercepting the desired signals from such a great distance. Another challenge was ensuring that the design was adapted to handle the large number of signals that would be intercepted by the satellite. We created a model to determine the probability of intercept on the desired and the interference environment from the other radar signals that might be in the field of view, de Broekert explained.
“My function was to develop the system concept and to establish the system parameters. I was the team leader, but the payloads were usually built as a one-man project with one technician and perhaps a second support engineer. Everything we built at Stanford was essentially built with stockroom parts. We built the flight-ready items in the laboratory, and then put them through the shake and shock fall test and temperature cycling…”

Agena and Ferret Subsatellite credit: USAF
Like the cover story for the CORONA (which called them Discoverer scientific research satellites,) the first three P-11 satellites were described as “science” missions with results published in the Journal of Geophysical Research.
Just fifteen years after Fred Terman had built Electronic Intelligence and Electronic Warfare systems for bombers over Nazi Germany, Electronic Intelligence satellites were being launched in space to spy on the Soviet Union.
Close to 50 Ferret subsatellites were launched as secondary payloads aboard Agena photo reconnaissance satellites.

Yes We Can – Dumping Detente – Bill Perry and “the Revolution in Military Affairs”
After 20 years of an escalating arms race, the Nixon administration decided to take a new approach to dealing with the Soviet Union: Détente. Kissenger’s thinking was: history may be tilting to the Communists and we may not be able to win the struggle with the Soviet Union so let’s settle for parity. Yet while the U.S. had been engaged in the Vietnam War, and had agreed to parity in nuclear weapons, Soviet forces in Europe had built a 3 to 1 advantage in tanks, artillery, armored personnel carriers, and soldiers, all under Détente.
In response the U.S. dumped Détente and embraced a new strategy to counter the Warsaw Pact by not matching them tank for tank or solider to solider. The new insight was that we could change the game completely and take advantage of a lead we had that was getting longer every day – by using our computer and chip technology to aggressively build a new generation of weapons that the Soviet Union could not.
At the heart of this idea was something called “precision strike,” what we would today call smart bombs or precision guided munitions. But this new strategy was more than making the bombs smarter. It involved building stealth aircraft to deliver these precision weapons unseen by any enemy radar, and designing intelligence and reconnaissance systems that would target for them. Smart weapons, smart sensors, and stealth. And the heart of all of this were microwaves, silicon chips, electronics and computers that only the U.S. could design and produce, and a good part of it was coming from Silicon Valley.
The Arms Factories that Won the Cold War Were Semiconductor Factories
Who was the government official pushing all of this? It was none other than Bill Perry, who had become the head of Research and Engineering for the Defense Department. From 1977 to 1981 Perry cranked up spending for research and development on a massive scale. The budget for the Defense Advanced Research Projects Agency (DARPA) doubled, and huge “smart weapons” defense programs like the F-117 stealth ground attack plane and the B-2 stealth bomber; precision guided munitions; JSTARS, a surveillance system; and the satellite Global Positioning System (GPS); MX missile; Trident submarine; and Tomahawk cruise missiles.

F-117 Nighthawk - 1st Stealth Ground Attack Plane
These changes in American defense policy spooked the Soviets. The Chief of Staff of the Red Army said that this “Offset Strategy” was revolutionizing contemporary warfare and posed a military threat that the Red Army could not match. “We cannot equal the quality of US arms for a generation or two. . . . We will never be able to catch up with you in modern arms until we have an economic revolution. And the question is whether we can have an economic revolution without a political revolution.”
The U.S. Cold War strategy had gone from a “let’s be friends” to a “yes we can win” strategy. By the mid 1980s Ronald Reagan was cranking U.S. defense spending even higher. Gorbachev, now the Soviet Premier, had to grapple with the spiraling cost of military systems that weren’t amortized by consumer purchases. Arms control with the U.S. and massive cuts in weapons and the military seemed like the only way out. And the rest is history.
Bill Perry put us on the path to use Silicon Valley as a weapon in the cold war.
