Directorate General of Army Air Defence General Staff Branch Integrated HQ of MoD(Army) has issued a Request for Information (RFI) 938 Air Defence Guns alongwith 5,05,920 Rounds [(3,42,720 (HE Rounds) &1,63,200 (Smart 3P Rounds)] on 27 November 2018.

The RFI is issued under the standard, no cost, no commitment bases with the Ministry of Defence, Government of India, reserving the right to change or vary any part thereof at any stage.

The proposed gun is planned to replace the L-70 and ZU-23MM-2B Guns, currently held by Army AD. The Air Defence Gun will be employed for providing terminal AD to critical VAs/VPs in HAA/mountainous terrain/plains/deserts/semi-deserts.

The RFI is issued under the Buy (Indian IDDM) category in  terms of indigenization content given in Para 6, Chapter I of DPP 2016 (for gun and ammunition both)

Buy (Indian-IDDM)? category refers to the procurement of products from an Indian vendor meeting one of the two conditions: products that have been indigenously designed, developed and manufactured with a minimum of 40% Indigenous Content (IC) on cost basis of the total contract value; Or products having 60% IC on cost basis of the total contract value, which may not have been designed and developed indigenously.

Apart from overall IC as detailed above, the same percentage of IC will also be required in (a) Basic Cost of Equipment; (b) Cost of Manufacturers? Recommended List of Spares (MRLS); and (c) Cost of Special Maintenance Tools (SMT) and Special Test Equipment (STE), taken together at all stages, including FET stage.

The onus of proving that the equipment design is indigenous, rests with the vendor and such vendor claims will be verified by a committee comprising scientists from DRDO and representatives from SHQs, based on documents issued by authorised agencies and presented by the vendors.

The supplier has the option to indicate if the Buy IDDM category is suitable for it.

The proposed gun will be employed for providing terminal AD to critical VAs/VPs in HAA/mountainous terrain/plains/deserts/semi-deserts

Operational Characteristics of the Gun

The gun should be able to engage air targets independently with the in service fire control radar and EOFCS by day & night.

The gun should have the capability to engage fighter aircraft, transport aircraft, helicopters

(including hovering helicopters), Remotely Piloted Aircraft (RPA) / Drones, Cruise missiles, PGMs, RAM (Rocket, Arty & Mortar), Micro light aircraft, para motors, Para gliders and Aero models.

The Gun should be capable of min five or more effective engagements of continuous fire without barrel change.

 Technical Parameters.

The proposed gun is required with following technical parameters:- The gun should be able to engage air targets both with and without in service fire control rdr.

The gun should be capable of being towed by an in Service gun towing vehicle for employment in mountainous terrain / HAA and should be vehicle mounted on an in service vehicle for employment in plains / semi-deserts / deserts.

The gun should be able to engage air targets during day and night using in service fire control rdr as well as Electro Optical Fire Control Systems (EOFCS) independently.

The Gun should also have the provision to engage air targets with in service fire control rdr at the time of evaluation.

 The gun should be able to fire smart / advance ammunition in addition to standard ammunition.

(iii) The gun should be capable of firing the following types of ammunition:- (aa) Programmable ammunition with self-destruct capability (3P/ AHEAD or similar ammunition & not Air Burst Ammunition or PFFC). (ab) High Explosive (HE) rounds with self-destruction capability and tracers. (iv) Appropriate quantity of dummy low cost contemporary training ammunition to be provided. (v) Adequate ammunition stowage for more than five effective engagements.

Stowage / reloading should be possible with two or less personnel. (vii) The reloading is to be completed within 10 mins. (viii) Ammunition should have shelf life of at least 10 years, which may be extendable after inspection by competent authority.

Hit Probability. Hit probability of minimum 0.6 during one effective engagement cycle. (k) Operational Altitude. Minimum 4.5 Kms above Mean Sea Level. (l) EOFCS. (i) The gun should be capable of engaging air targets using the EOFCS when it is operating without fire control radar during day & night. (ii) EOFCS should comprise of a lead computing sight having a CCD camera, TI Sight, LRF and auto tracker or similar equipment based on vendor configuration. (iii) EOFCS should have the following features:- (aa) Enable acquisition of target with open sight with a field of view of minimum 40 degrees (ab) Should have adequate tracking range so as to enable the engagement of target at the max effective range of the Gun (tgt speed upto 500 m/s) (iv) In case of temporary failure of electronics of EOFCS, a facility should be provided to engage the air targets through open sight giving necessary lead angles.
