Our current capability stands at 10 tons to LEO with a 4 meter dia fairing on GSLV mk3 . Getting to 100 tons will require atleast 2 intermediate waypoints. Maybe 20 tons by end of 2030 using semi-cryo and 50 tons by 2040. This is all linear scaling and unless someone disruptive comes along in Indian...

With CCM that has IIR, loosing lock will be less of a problem than non IIR plain vanilla types like sidewinder since former has got some 'intelligence' inside to see whats going on. Plus you will be homing in from quite some distance with datalink support and it would be extremely difficult to move ...

If its uncooled, it could be operating in low portion of SWIR. There are commercial SWIR cameras available for industrial monitoring in which cooling is based on convection alone. Tonbo might optimized their camera for 2.5 km application and offloaded the image to the onboard processor that will tak...

Lot of creative ideas thrown here in last couple of posts.
Even P8Is that overflew Ladakh were capable of dropping Mk54 torpedos. That thing could sink a tank by momentum alone.

With Navy planning to lease Panther helicopters, KA 226 case becomes even more weaker. With wrangling going on over indigenious content, It will eventually become a non-starter. Ideally Kamov should have targeted utility providers or farming companies for this jack of all trades.

It is a good idea to place a radar below, given it is storage bay anyways and it is empty. If it is some sort of rear facing radar, we might have a 360 coverage. Or a SAR like the famous Sentinel. With GaN modules, even the kitkat on the top coupled with radar on the nose, we will have a cost effec...

Congratulations to all involved in this achievement. May this be the beginning of long order book to flow in next many years.
Hope this makes LCA case stronger for US Navy trainer requirement.

French also recently offered TALIOS. One more import and it will be kichdi.
Leonardo's expendable decoy Britecloud is something we should try to get since we dont have any in our fleet.

So the nose seems like holding an AESA going by the shape of it. If true and if its X band, I am salivating at the range it will be able to lock on given the power the platform can provide. I hope we develop an ultra long range air to air solution to take advantage of this.

Quite impressive they used the 5th pylon of 747 to launch the 30 ton rocket. Able to place 300kg in polar orbit with a 2 stage rocket strapped to a commercial airplane is amazing. They are aiming for 100kg to moon, 70 kg to Venus and 50 kg to Mars in future. Changes the way inter planetary explorati...

Typically, that does not require big changes to the airframe. But it places restrictions on the envelop and a lot of time in qualifications. Thanks.

Nice.
Since it's a major redesign going by recent tender, any chance of putting floats

We already have the ELM 2060 on Su 30 that takes care of its SAR needs. That and P8i takes care of immediate requirements.

Actually a large UTTAM based X-band radar opens up other things besides just EW. It could be a handy capability for generating SAR maps, and even tracking cruise missiles more precisely at least in a sector. With more workstations and crew it does open up some possibilities. Yes this is exactly wha...

If we are going with the kitkat, I am hoping Airbus figures out a easy way to put a radar for frontal 60 degree coverage. If we manage 260 degree with the panel like the Wedetail, then frontal arc is 40 degrees. 300 degree coverage will be pretty good. May be a custom nose... Maybe put a X band lik...

With Boeing tasting success with its 737 series as ASW, Airbus might want to push A320 series into some military role. This might be an opening for them.

Since the modification is to be done in europe, guess they are planning it on A321.

For UAV engagement, we dont seem to have something similar to RPS-42 S-band radar by RADA, Israel. Hope DRDO develops something similar as part of biho replacement.
