In July 2024, DRDO's 'AD Launch Site' for future BMD tests was suspended due to fishermen's concerns regarding temporary restrictions during missile tests. The new Chief Minister has stated that the project has now been approved and fast-tracked.

Progress on DRDO's 'AD Launch Site' in Junput, West Bengal is now visible on Google Earth's updated imagery for the month of April. The launch pad will be used to fire target ballistic missiles for upcoming tests of India's Ballistic Missile Defence (BMD) systems.

The Agni-V Mk2 (Divyastra) is an advanced, MIRV capable iteration of the Agni-V. Major improvements include replacement of maraging steel first stage casing with one manufactured using carbon composite filament winding, it is India's largest composite casing for now.

As mentioned by @GODOFPARADOXES, the Post Boost Vehicle may be separate from the 3rd stage.

That, combined with the use of electromechanical actuators, rather than electrohydraulic ones, for the flex nozzle control for all stages, have lead to weight savings as compared to the baseline Agni-V, which weighed around 50 tons.

DRDO-LRDE's airborne radars can be categorized based on the architectures being used. The plank architecture (Uttam) supports dipole antennas. The newer, more compact tile architecture (Virupaksha) can house high bandwidth Vivaldi antennas. New details are discussed as follows:🧵

Possible correction: On counting the QTRMs on available diagrams, the TRM count for the newer iteration of the LCA AF Mk2 radar comes out to 952. However, the document used as the basis of the original post mentioned 968. Make what you will of that.

Felt obliged to post an update regarding this & the accompanied assertions: CVRDE has recently issued RFIs seeking partners for a new 1500 HP engine & transmission. The powerpack, named CV1500A, is confirmed to have a T-type config (longitudinal engine, transverse transmission).

The 1500 hp powerpack is a U-shape config. Won't fit in an Arjun engine bay without redesign. Some mod might be done in the test vehicles, but how long does that take from there to production Mk.1As, if at all, is anyone's guess. That is why, imo, the old setup might stay.

There are indications that both Su30 and AMCA's radars will have the same power output. If this turns out to be the case, the AMCA radar TRMs will require a higher peak power output (due to lesser TRM count) than that of the Su30 radar (likely 10W).

HAL will be procuring 140 antenna units of the Tejas Mk1a's Uttam AESA radar from Astra Microwave Pvt Lmt (AMPL) in two batches of 33 and 107 units. The combined cost of AMPL's quotations for both batch orders is Rs. 2,760 cr ($320 million at present exchange rate).

The Uttam radar for Tejas Mk1a is an X-band AESA radar with 912 TR modules. The first batch of 33 units likely caters to the 2021 order of 83 aircraft (73 Mk1a + 10 trainers). This is because, as per @delhidefence, the first 40 units of the Mk1a will feature the Elta 2052 radar.

The second batch of 107 units will likely serve the upcoming order for 97 more Tejas Mk1a aircraft for which HAL has already begun procurement of LRUs in anticipation. With these orders, the Uttam AESA for LCA Mk1a will become the first Indian airborne radar to be mass produced.

This is misinformation. Users should note that Chinese firm MizarVision, which released post strike imagery of PAF's Pasrur and Chunian radar facilities used by the OP, assessed that the facilities were indeed damaged.

The Chinese imagery provider Mizarvision appears to be validating IAF strikes in Pakistan ? - undated images but analytical language suggests damage

A look at the technical specification of the AESA-AAAU for LCA AF Mk2: It features 912 TRM with 896 active elements, and 16 receive only elements. 10W GaAs TRMs, similar to the Uttam for Tejas Mk1A. The new antenna is shorter in height but wider, to fit in the smaller nose frame.

There has been some uneducated guesswork going around Mk2 using GaN TRMs, that is false. The peak transmitted power is ~8.9KW. Transmit output power (min): 10W (peak) per TRM Transmit output power (max): 16W (peak) per TRM All TRMs can not operate at 16W with the 5.5KVA AAPSU.

HAL has issued two RFI for the design development and supply of two radar systems for DBMRH variants: AEW radar for the DBMRH-AEW variant and Surveillance radar for the DBMRH-S (Special Ops variant). D&D activities and production facility should be established within T0+60 months

AEW system should be made available by June 2027 for fitment on the DBMRH prototype. The RFI is open for both Indian and foreign vendors under Make in India. The desired specifications for the AEW system are mentioned below:
