Project Kusha / Programme LRSAM / PGLRSAM
- Thread starter Fatalis
- Start date
Yeah for economy of scale they will keep the metallic casing. But I was wondering about since the Kusha longest range version would use a very powerful booster, so would be costly anyway and in that case a composite propellant based high powered crmc one would be more useful or not.
Just want to see what small or big gap there would be between like AD-1 article and Kusha M3. Theoretically both can work against some TBM of 3000km range?
ASL CPDC got the crmc expertise (plus the jet vanes, graphite, C-Sic etc prob), and with the LRAShM they probably now made a system for conventional use non strategic. Hence curious whether that knowledge can now expand into long range conventional systems to create its own economy of scale? Like something air launched that has metallic booster casing but with a miniaturised C-C made glide body kv? ie expanding rudram series horizon a bit more.
Fair point. Although to take full advantage of the CRMC, both the booster & the main body needs to have it.
ASL is now in the process of acquiring 6-axis collaborative robots with torque sensors to automate laying down/rolling the fiber to make CRMC. The advantage of this process over the current set ups it that it is not specific to the size of motor. Theoretically this process, when fully deployed, can make CRMC of any diameter & length as long as there are fixtures can support that casing during winding.
VRDE tendered out the transporter vehicle of LRSAM. NDA so only metric we get is the vqc
Looks like Israel is also working on similiar concept as that of Kusha.
Israel's IAI Barak MX air defense missile system has been further expanded. In addition to the 15km range, 9km altitude Barak-SR, previously mentioned in the product brochure, a new member has been added: the 250km range, 35km altitude Barak-EA. It appears that the Barak-EA has been replaced with a longer booster and a new electro-optical sensor guidance head (multi-mode).

Looks like RF+EO/IIR guidance (based on the conical radome and offset EO seeker window) which reportedly Kusha will also have.
Just my thinking, the M1 should have been delinked from the overall Kusha program and paired with the existing MRSAM system to create 2 influence bubble zones at 70 km and 120-150km area of responsibility. I did not understand how they used a same KV config for all the 3 ranges. M2 M3 could operate in 220 km, 300km area of responsibility with the same KV, but there should be one M4 with an improved kv, perhaps borrow the KV of AD-1 with pairing on top of the AD-AM booster stage. This would be a very long range killer that can take on any large threat at very high distance.
They use that Indhan-1 propellant for many purpose now, must have good value and some slight different combo for one more variant. The light green booster motor of M3 was definitely of higher dia so possibly a more powerful stage.
What are the main differences between the KVs and radar seekers of short range interceptors and long range interceptors? I would be grateful if you explain this.
The top part is called the kill vehicle, a fully integrated akash ng sort that is used as the top stage as a whole integrated missile/rocket whose job is to intercept a target. It can be kinetic kill vehicle kkv with direct hit, or just indirect hit with large warhead effect.
Entire system is the launch vehicle LV, booster section and kv section together. Boosters job is to propel it up, cross certain distance & lift the full LV to a certain altitude or give certain working kinetic thrust, or both, from which the KV takes over and does the rest of the job ie interception of the target vector.
Radars seekers proximity fuzes are part of electronics package, one section of the kill vehicle. Seekers seek the target from a certain distance in the terminal phase & locks on to it. Then when nearby the rpf goes off and warhead triggered via sam safety arming mechanism. A kinetic kill vehicle (with or without warhead) like the ASAT need very high precision targeting capability so uses the all aspect IIR seeker because a direct hit is the criteria, miss distance is zero. Otherwise a kill vehicle with warhead allow for a small miss distance as the warhead blast & fragment dispersal do the job.
It will be interesting on the kusha front in the near future
3 type of radars and 2 type of control and communication centers?
For radars:
1. LRBMR
2. MFCR
3. May be some mast mounted radar.
Has to be for kusha since 12 x 12 truck ? TLV means transporter cum loader vehicle.
By casing dia maybe, you can simply change the propellant grain config (front/aft finocyl to conocyl, or any other geometric shape) , burn rate (progressive/regressive & neutral) and propellant combination (high smoke content single/double-triple base homogeneous, less smoke Al rich composite) to suit for completely different performance requirement. I think we know the booster config will use the Brahmos propellant combination grade, right ?
