Gravity+ Dual Pulse motor gives a phenomenal capability in the kill zone for Derby ER. Plus allows you to keep the missile smaller as well. I always admired how a 250 kg Barak8 (almost equal in weight to a BVR) is able to go 70KM from ground level.

I hope DRDO hasten Astra development with dual pulse motor.

Someone please answer the following question:
Is India uninterested in making close combat AAMs?
a. We are uninterested
b. We do make - its called <fill in the blank>
c. They are easily available - we simply buy off the shelf
d. No seeker, so we are stuck

Different missiles with different end goals. Derby ER is still a SRM with a second kick for end game kinematics while Meteor is designed around sustained higher speed compared to a standard SRM so it will fly out faster for a given range. A VFDR is designed to essentially create a slower degradation in velocity compared to a SRM post burn out but is throttelable while a second kick stage will still not prevent the loss in speed that you will see post first stage exhaustion.

Although one can essentially control the second pulse trigger and have it go off as soon as the initial motor burnout you will loose on range by doing that. There is an AIAA paper from Raytheon that looked at a dual pulse and multi stage AMRAAM, Liquid fueled Ramjet AMRAAM and the a VFDR AMRAAM. Before the USAF shifted focus to faster missiles that can get to a target faster the trade space clearly showed a preference for VFDR for best overall performance. Dual pulse was identified as the lowest risk and cost upgrade but inferior to a VFDR or other simpler ramjet applications. None of these are without a penatly of course. The Meteor is largely the same size as the AMRAAM yet carries with it a good 25% weight penalty so there is no such thing as free lunch.

India contracts IAI for nearly USD2 billion of air and missile defence systems

http://www.janes.com/article/69373/indi ... ce-systems

The contract, which IAI values at between USD1.6 billion and USD2 billion, will see the Medium-Range Surface-to-Air Missile (MR-SAM) system delivered to the Indian Army, and additional Long-Range Surface-to-Air Missile (LR-SAM) systems delivered to the Indian Navy (IN).

MR-SAM has been co-developed by Rafael and IAI's Elta division in conjunction with India's domestic industry and state-owned Defence Research and Development Organisation (DRDO) as a development of the Barak 8 (Lightning) missile system (now re-designated Barak Long-Range [LR]). The system has a range of 70-80 km, and is comprised of an advanced 360 degree phased-array radar, command and control systems, mobile launchers, and radar-guided missiles. As previously reported by Jane's, the MR-SAM deal envisages five missile regiments comprising 40 firing units and 200 missiles, with deliveries expected to begin in 2023.

The Barak 8 will initially provide air and missile defence for the INS Kolkata , INS Kochi , and INS Chennai guided missile destroyers. The follow-on deal announced by IAI is for systems to equip the service's first domestically-built aircraft carrier; INS Vikrant . Officers have told Jane's that the LR-SAM is capable of simultaneously tracking multiple seaborne targets out to 25 km and fighter aircraft out to 250 km. Modelled around a multi-functional phased-array radar, the system comprises command and control systems, vertical launchers, and missiles.

There was a talk at aero india seminar this year by the developers of the propulsion system about the challenges of developing the system (harmonics). They initially had catastrophic failures with the entire motor blowing up. They have solved the problems. It was a great learning experience which resulted in a great product.

If you look at this poster, Astra Mk.1 is a dual purpose AAM--CCM and BVR. CCM with 45 degree offbore-sight launch and slaved to HMD. LOAL and LOBL are both supported. If an IR seeker is made interchangeable with current RF seeker, then we have something similar to MICA.

Indigenous seekers (IR/RF) would help a great deal. Everything else has been mastered it seems.

The nozzle and the super high speed exhaust act as acoustic vibration generators. Mostly random sine vibration.

Same as a trumpet driven by super high speed gas.

New Indian Order Brings Barak-8 Order Book to US$ 5 Billion
http://defense-update.com/20170406_mrsam-3.html

This article has details on $$$ breakdown. Total contract value $2.5B. DRDO portion is $900M and IAI part $1.6B.

Israel Aerospace Industries (IAI) and the Indian Ministry of Defense signed a contract worth US$1.6 billion today, for the supply of an unspecified number of Medium Range Surface to Air Missiles (MRSAM) for the Indian Land Forces

The contract reflects the Israeli part of the $2.5 billion MRSAM order cleared by the Indian government in February this year. A third of the program is allocated directly to the Indian partner – the government managed Defense Research & Development organization (DRDO).

India to export lightweight torpedoes to Myanmar

From AW&ST

NEW DELHI—India will soon supply indigenously-developed lightweight torpedoes to Myanmar in a deal worth about $38 million.
The torpedoes will be developed by the Defense Research and Development Organization (DRDO), India’s state-run military agency, DRDO Chairman S. Christopher says.

The system will be developed in collaboration with the public sector undertaking Bharat Dynamics Ltd. and private engineering and construction company Larsen & Toubro Ltd.

The export of the lightweight torpedoes “would follow the earlier supply of sonars, acoustic domes and directing gear to Myanmar,” Christopher says.

The DRDO official did not disclose a time frame for delivery of the weapons.

India shares a long maritime boundary with Myanmar and is already providing night-vision devices, Bailey bridges, rocket launchers, mortars, rifles, communication and Inmarsat sets to the country’s armed forces.

India earlier accepted a proposal from the Myanmar Navy to train Indian Navy personnel and set up meteorological facilities.

New Delhi’s stepping up of military support to Myanmar comes in response to Yangoon’s interest in deepening the countries’ security ties. The two sides have also coordinated patrolling in the boundary along the Bay of Bengal.

Maitri (IN SRSAM) is all but redundant. It existed purely because IN was unsure that DRDO had the tech to make ARH compact missiles. Astra itself was in development issues. Today, QRSAM exists and is well along development. Astra has also cleared multiple trials and an indigenized version of the original Russian seeker has also been tested. My take is that Maitri will be cancelled. DRDO no longer needs the French assistance as it once did or was perceived to have needed.
IMHO - the missile programs will be:

Local:
Akash : 25km range
Akash1S (upgraded with RF seeker)
Akash NG (50km range)
QRSAM/SRSAM for IA/IAF and perhaps a variant for Navy. 20-25km range performance in a much smaller footprint (comparing with ramjet Akash is not apples to apples).
Future QRSAM/SRSAM variants with extended range missiles (using Astra derivatives)
XR-SAM: Long range SAM 100km+

JVs:
Barak-8 and ER variants: 70km-100km


Karan I don't think Akash NG or Akash with RF seeker will ever see the light of day. There have been no reports about Akash-MK2 or Akash-NG for a long time. Plus we do not yet have a RF seeker ready for production.
With the recent signing of contract for the Barak-8 for the army, that too for a projected 5 regiments, the army requirement is over. Navy will not field the Akash and with the production for MRSAM for the IAF yet to commence, I don't think the IAF is looking for Akash-MK2 anymore. IAF is set to get a minimum 10 squadrons of MRSAM.

Sad to see that even after placing order for almost $3-4 billion worth of orders for the Barak-8, we are still not able to get the seeker tech for the same.
Apart from the current order placed for the Army and the Navy order, which is only for the Vikramaditya, we have already placed order for P15A, P15B ships and are in the process of placing order for P-17A ships. The upcoming Vikrant will also get the system. Apart from this, IAF is set to get upto 10 squadrons of MRSAM and the number may go up in the future.

Akash 1S is a definite. It's an upgrade path for Mk.1 in service with the IAF (8 squadrons) and IA (2 regiments). There are another 7 squadrons in order by the IAF. A couple of years ago there was a report of another 15 squadrons being planned by the IAF. Makes sense for Akash Mk.2. The IAF has stated that its requirements for SRSAM is fulfilled by Akash. There is a separate 9 squadron order for LLQRSAM (Spyder).

The biggest selling point for Akash SAM is its price. It's super cheap when compared to Barak-8 MRSAM. Akash (SRSAM) and Barak-8 (MRSAM) fulfill different space in the air defense roles. 5 regiment of S-400 (LRSAM) is being negotiated.

Barak-8 is a JV where each side get its own part of technology agreed and build the system , There is no tech transfer for Seeker or MFR from Israel nor will DRDO part with its dual pulse motor technology , actuators or other they are building for this.

If in future DRDO manages to build it own seeker by itself it can integrate into Barak-8 system but that will be a long and gradual process wont happen initially

Your statements are incorrect IMHO.

The latest Standing Committee on Defence reports clearly mention GOI has funded Akash NG and DRDO/BDL have confirmed Akash 1S.

DRDO annual report notes the indigenized seeker for Astra is ready and in trials. Apart from this, there are other programs underway.

IAF has asked for additional Akash squadrons and that is separate from the more expensive MRSAM of which 9 squadrons only are ordered.

Akash variants will be in the 50km range and will ve more cost effective than the MRSAM.

IA will not go for Akash but QRSAM variants.

Mody, read MOD Annual Report 2016.

IAF section. " In future IAF plans to induct further advanced versions of Akash missile system. These are important for providing defence to vital areas and vital points"

Akash NG and Mk1S are mentioned in DRDO section.

Tying this with other reports:

Mk1 will be replaced by Mk1S while Mk1 is also cleared for export, and Mk2 will meet future IAF requirements.

QRSAM flight trials in 2017.

Akash 1S is program to prove retrofit ability of AR seeker to existing Mk1 missile for upgrades. Clearly shows the intent.
Akash NG, 50km, ten target engage system. Designed clearly for surge attacks.

Ashwini LLTR has entered trials, Arudhra has already completed several. Point being enablers of a local SAM network above and beyond Akash are also well underway. Arudhra can detect a 0.1 Sq Mrt target at 100km plus.

^^^When we look at quantum of stuff likely to be purchased, it is always advisable to start from basic - i.e. present strength of the system being replaced by new system. Unless, it is a system in a new category like MRSAM for IAF and IA.

In case of Akash, IAF has/had about 30 missile squadrons equipped with SA-3 SAM. Required to cover all their bases and other Vital Areas/Vital Points in context to IAF. Akash is required to provide AD cover in immediate vicinity of an AFB or VA/VP; - even if IAF does not go for 1-on-1 replacement for SA-3 system, we're still going to see between 20-25 Akash squadrons in IAF service.

IA is a different story. There the QR-SAM will proliferate. But I'm hopeful a few more Regiments of Akash (1S or NG) will come to cover static formations.

Rohit, its QRSAM all the way for the Army. More Akash if they come will be Mk2 version.

BTW, looks familiar?
https://3.bp.blogspot.com/-oa_iJMCpmUQ/ ... BADTCR.jpg

Think current TCR but AESA. Yet QRSAM BSR will have more range. And better resolution.

https://3.bp.blogspot.com/-M1BUFCyN7DI/ ... 2BBMFR.jpg

So QRSAM will be potent by itself.

Code: Select all

Astra        Mk.1       QRSAM/Mk.2
Weight      154kg         200kg
Length      3.57m         4.4m

The range for the beefed up QRSAM Astra is 30km. Looks like that may form the basis for Mk.2 100+ km variant. It probably is a dual-pulse rocket motor one. Foldable fins good for internal weapons bay (stealth external pods, FGFA and AMCA).

Spyder is 15km using standard Python-5 and Derby AAM. Range of MR-AAM (60+ km) typically translate to around 15km when ground launched without any boosters. So that would mean 30km Astra QRSAM would mean a 120km AAM variant.

600kg NGARM. I think DRDO may be building a series of multi-purpose missiles on that frame with different warheads and seekers.

Sputnik cites Russian Defense Ministry spokesperson Maj. Gen. Igor Konashenkov as indicating that only 23 of the 59 Tomahawk Cruise Missiles launched by the American’s made it to their target in Syria. Konashenkov is reported as saying he did not know what happened to the other 36. Anyway 36 is a lot of dud missiles:

The spokesman {Russian Defense Ministry spokesman Maj. Gen. Igor Konashenkov} suggested that it was noteworthy that only 23 of the 59 Tomahawk cruise missiles launched from US Navy destroyers made it to their targets at Ash Sha'irat. "It is not clear whether the other 36 cruise missiles landed," Konashenkov said, without offering any more details.
