Current range of LRTR 3?
If I am not mistaken LRTR is a swordfish radar right? And how different it is to VLRTR?
Very long range tracking radar has a range higher than 3000 km. LRTR 3 has a 2500+km range.
LRTR and it's variants come under the aegis of IAF.

Very long range tracking radar come under the command control of NTRO. They are NTRO assets. Although IAF officers and NCO are on deputation to NTRO to man and operate these radars .

DRDO Coastal Surveillance Radar
DRDO CSR.jpg

DRDO CSR2.jpg


design is to detect and track small fishing vessels for Coastal surveillance application. can also be directly used for Vessel Traffic management Services, harbor surveillance and navigational purposes. By mounting
on ship, it can also be tuned to the role of Sea Surface Target Surveillance Radar. It can be used for Airport Surface Target Surveillance as it is solid state coherent radar with Doppler processing.

Air Marshal HS Arora PVSM AVSM ADC, Vice Chief of the Air Staff (VCAS), witnessed Surface to Air Guided Weapons Firing as a part of Combined Guided Weapons Firing 2020 at Air Force Station Suryalanka on 01 Dec 20. Indigenous Akash Missile System along with Russian short range Igla missiles were fired and engaged the Manoeuvrable Expendable Aerial Targets (MEAT) providing near realistic training to the combat crew. VCAS commended the participating combat squadrons for their professionalism and also appreciated the efforts put in by the Station for organizing this exercise with requisite COVID precautions. He urged all the air warriors to be ready to apply all lessons learnt in the CGWF 2020 to any emerging operational scenario.

The 341 TRU transportable radar unit of IAF is an Indra 2 radar unit.

The 121 TRU is a Rohini CAR unit.

Indra 2 is a 2D L band low level airspace surveillance radar. It differs from Indra 1 in that it uses pulse compression . These are gapfiller radars meant to complement the Russian ST-68U Tin shield radars in IAF service .

The Akash Sam squadron which participated in the exercise is 2409 squadron. They have a cheeky tag line in sting and kill.
