Does that mean that Astra will be part of the weapon system of MIG 29, SU- 30MK1, LCA etc.

Can this missile kill a F-16 of Pakistani Airforce over Sargodha from the Indian border.

Almost all bvr have a fifty percent success rate. It would not be guaranteed.

Re: CLGM: Cannon Launched Guided Missile

but the point being missed here is

as per DRDO report

DRDO is working on AESA radar seeker for misslies (probably a2a and s2a)

Having an AESA on missile will make it less dependent on the originating aircraft for guidance, further my query is that if using two way link and AESA radar seeker missile would it also be able to extend the range of detection of originating aircraft to an extent (depending on range of the missile)

i think not

'coz

missile will be launched only after lock on by aricraft radar
and aircraft radar will obviously be more powerful than missile radar

bu tthere is a catch

in a scenario that the missiles are launched at the edge of thier range and soon after the launching all missiles the aircraft simply turns back than it that case 2 way link may provide the rear picture of the battlescence to the aircraft through the missile radar
and
in that sense extend the radar range of the aircraft

I did mean more or less the same. LCA will detect the enemy and when it is within the missiles firing envelope, it will be fired and the plane heads back, and during this time, both the AESA of the missile will be scanning the area while it tracks and goes for the target providing the pilot with more situational awareness. Then the pilot can either head back or fire a parting shot against another target that has now been found.

Sir, AESA on missile will only help in terminal phase with Low Probability to Intercept, difficulty to jam and more resistance to passive counter measure.
The missile with require mid-course updates from aircraft till it reaches the terminal phase and the enemy air-craft comes in its seeker range.

Until the enemy aircraft reaches missiles seeker's tracking range someone will be needed to guide the missile. In most case it is the launching aircraft and in network centric warfare some other aircraft with more powerful Radar like AWACS.

Even if the target aircraft is in seeker's tracking range the launch aircraft will have to keep an close eye on enemy because their is no 100% hit probability. Chance that the missile miss target are more than it hits target in dense/complex EW environment like that between PAF and IAF. If the pilot becomes careless he may himself be shot down.

Currently most radars give capability to engage 4-16 targets and track 8-64 targets.
Tracing and mid-course updates is handled by the radar computer.

Air to Air combat is not like artillery combat that you shoot and scoot. In Air to Air combat someone has to stay till you for conformation of hit or miss.

AESA will ensure harder to jam, Harder for enemy aircraft`s RWR to make out source of guidance also the band as AESA has ability to change multiple band waves ( Their are other radars does the same but not same as AESA ) ..

An Missile seeker is design to operate at some range until then its guided by more powerful AESA from other aircraft ..

Hard to say this is for Astra but may be for Akash or PAD as the AESA seeker or radar are heavy compare to other traditional radars as they are liquid cooled not air cooled for cooling means extra equipment ..

The solution here can be GaN based MMW AESA seekers- Please refer to the "EMERGING
TECHNOLOGIES" section in the following document-

http://www.drdo.gov.in/drdo/pub/techfocus/2008/oct08.pdf

It would also help in smart cluster arrangements for tactical battle field missiles-

India will be conducting the final round phase trial of Astra, beyond visual range (BVR) air-to-air missile on March 12 before inducting it in its Armed Forces.

Defense Research and Development Organization (DRDO) has begun preparation for a fresh trial of the indigenously developed missile from a defense base off the Odisha coast.

"The Astra team has arrived here and they are busy in integrating the missile components. If everything goes as per plan and weather is favorable, the test would be carried out targeting an unmanned aerial vehicle as per schedule," Indian Express quoted an unnamed source as saying on Monday.

The test is likely to be conducted in association with a team of Air Force officials on March 12 at the Integrated Test Range (ITR) at Chandipur-on-sea.

The missile, sanctioned in 2004 at $1.5 billion, was test fired in May last year over the Arabian Sea off Goa and was declared a success following a host of technical glitches like a defective aerodynamic configuration since its conception.

The BVR missiles are quite complex, with rocket/ramjet propulsion, micro-computers, active radar guidance/inertial navigation systems, terminal radar frequency seekers and the like - since they have to effectively destroy highly-agile supersonic fighters packed with "counter-measures" at long ranges.

Can someone please share the results of the tests (scheduled today) as well as the roadblocks ahead of inducting these missiles.....not sure which existing missile system it is intended to replace (Ignore my ignorance) after multiple rounds of improvements including but not limited to seeker.

Minor nitpick and may even be wrong but still you may need to take care a little.

AESAs can do phase changes and interference patterns to be able to generate a digital signal where you could be lighting up x position and in the next moment lighting up the y position without having to go through the whole lot of space between x and y positions unlike an analogue equipment.

But I believe that even an AESA cannot simply move around from one Bandwidth to another Bandwidth. Not even to the near-about bands like from S to L and vice versa.

Band is a bunch of frequencies (theoretically infinite) that are very near to each other and wherein the highest and the lowest frequencies (out of these bunch of frequencies) form the two boundaries of the Frequency Band. The bunch gets defined essentially by the ability of these frequencies to cause interference (constructive/destructive), unless some multiplexing techniques are used. The multiplexing will allow use of the same space/time domain to effectively cause 2 or more final signals.

If the transmitter has a capability to use these multiplexing techniques using several different carrier signals, then it can do frequency hop. But even these frequency hops will remain within the overall Band the AESA is designed for. This limitation whereby you remain within the overall Band getting decided not by the theory of interference patterns but by the amount of signal loss suffered if there is a mismatch between the design limit of the hardware (TR modules and swashplate) and the design limit of the signal.

You see the design of the TR modules (spikey ones for X bands and big clunky ones for L bands) have a bearing on the kind of wave these TR modules can produce. Moreover the space required between these TR modules also has to be specific to what you want to achieve as to frequency use. If the design of the TR module and the design of the space between these TR modules was not relevant then we would easily have multiple types of Multi-Band antenna. But we have only a limited type of Multi-Band antennas. Moreover since nobody, normally has access to hardware of others so they do signal-sniffing (like the Rafales sniffing the Su30MKI signals in the Cope Whatever Ex.).

Thus even AESAs have to honour the Band limitation/discipline. No escaping there.

Just my 2 phooti kaudi.

Normally no news is good news. If things do not work, somebody would definitely leak the info to the press.

BALASORE: A fresh trial of beyond visual range air-to-air missile (BVRAM) Astra was deferred on Monday, reportedly, due to a technical snag. The missile could not be launched though an unmanned aerial vehicle which was to be used as a target for the missile was flown from the Integrated Test Range (ITR) off Odisha coast. Defence sources said the missile was initially planned to be tested on March 12, but was rescheduled for Monday. A defence official associated with the mission said though the pilotless target aircraft was flown as per schedule, the missile could not be fired due to technical glitches in the system. ITR Director MVKV Prasad said there was a possibility of the trial on Tuesday or Wednesday. As part of induction phase trials, the test was aimed at checking the control system and its stability which would have propelled its quick induction into the Armed Forces. However, it is not for the first time that the missile has developed problem. In 2011, it had failed twice, but in 2012 and 2014, a series of developmental tests, captive flights and trials from fighter aircrafts was successful. The indigenously developed Astra is designed for an 80-km range in head-on mode and 20 km-range in tail-chase mode.

Astra test-fired successfully against simulated target

The indigenously developed Beyond Visual Range (BVR) air-to-air missile, Astra, was successfully launched from Sukhoi-30 fighter aircraft to hit a simulated target at the Integrated Test Range, Chandipur in Odisha on Wednesday.

The missile was tested to prove the manoeuvring capability against a simulated target and also to validate various subsystems. All the subsystems like propulsion, navigation, guidance as also the smooth separation of the missile from the aircraft were proved, according to Defence Research and Development Organisation (DRDO) sources.
The all-weather, state-of-the-art missile developed by DRDO can engage and destroy enemy aircraft at supersonic speed ( 1.2 Mach to 1.4 Mach) in head-on (up to 80 km) and tail-chase (up to 20 km) modes.

The 3.8 metre tall Astra is the smallest of the DRDO-developed missiles and can be launched from different altitudes. It can reach up to 110 km when fired from an altitude of 15 km, 44 km when launched from an altitude of eight km and 21 km when fired from sea level.
