First Scorpene Submarine Kalvari to join Indian Navy Fleet for Active Deterrence Patrol in July
At Aero India 2009, it was revealed that the 3D MMR project has been superseded by the new 3D AESA FCR project led by LRDE. This Radar has the capability for Air to Ground Mapping and Targeting. This ‘HYBRID’ MMR has successfully undergone trials and will be supplied for the initial LCA Tejas fighters of which 2 squadrons have been ordered.
Electronics & Radar Development Establishment(LRDE) is developing an indigenously developed AESA Fire Controlled Radar called ‘UTTAM’. It’s being developed for the LCA Mk-II and presumably Mk-I will be upgraded with the system.
Hardware has already been realized for this radar which has a range of more than 100Km against small sized targets and rooftop testing is underway. Though it currently weighs 120Kg which is less than the EL/M 2052, will be no problem in integrating it with the LCA Mk-II & Mk-I. It is a 3D for fighters, a MMR follow on, the APAR project aims to field a full fledged operational AESA fire control radar for the MK-II.
BEL has also developed a RADAR WARNING RECEIVER (RWR) which is designed for fitment on fighter aircrafts and helicopters. It intercepts, detects and identifies all types of ground and air borne emitters (Pulse, CW, ICW, Pulse Doppler, Pulse agile, Frequency agile) and presents them on cockpit display unit with the help of alphanumeric/special colour symbols and audio tones.
Hindustan Aeronautics Ltd (HAL) chairman T Suvarna Raju recently stated that as Indian Air Force has cleared specification termed Standard of preparation 2018 (SOP-18) for improved LCA Tejas MK-1P which clearly mentions incorporation of few key requirements such as air-to-air refueling probe, podded self-protection jammer, integration of AESA radar and improved maintainability of the aircraft. First improved LCA Tejas MK-1P according to agreed schedules between HAL and IAF will have its first flight by 2017 and enter production by 2019 for which IAF already has committed 108 AESA equipped MK-1P type while earlier 40 ordered LCA Tejas MK-1 will come with Israel Aerospace Industries/ELTA Systems-supplied EL/M-2032 MMR fire control radar.
State-run Defence Research and Development Organization (DRDO) which has taken up the development of flight control radar for fighter aircraft with 100 km range and multi-mode operation. AESA radar development which has been started under Project “UTTAM” is still few years from entering production and was in development to be used in Tejas Mk-2 and possibly in Mk-I. DRDO currently has placed Airworthy radar processor and exciter receiver on a high rise platform in Mechanical Scanned Array (MSA) configuration for validation of various algorithms and wave-forms of the fire control radar.
The IAF has also had concerns about the Mk-I’s turn-around time and wanted certain modifications not all of which could be executed on the Mk-I design which has obviously been frozen ages ago. Over the years there were also additional requirements raised by the IAF to keep the aircraft contemporary which included things like the integration of a supersonic drop tank and these were met according to Dr Tamilmani. Anyway concerns about maintenance apart, the Mk-I has shown its reliability by flying up to three sorties on a single day during trials in both Leh and Jaisalmer on several occasions.
Moreover the Tejas Mk-I acquitted itself exceedingly well during Iron Fist 2013 with its deployed weapons being bang on target during that demonstration. Also during IF 2016, the Mk-I demonstrated air-to-air capability by firing a R-73E missile and air-to-ground capability by dropping laser guided bombs (LGBs) directed by a LITENING pod carried on one of its pylons. It demonstrated Astra BVRAAM and Derby Air to Air BVR missile successfully.
ENGINE : However, progress in the Kaveri development program was slowed by technical difficulties. In mid-2004, the Kaveri failed its high-altitude tests in Russia, ending the last hopes of introducing it with the first production Tejas aircraft. In 2008, it was announced that the Kaveri would not be ready in time for the Tejas. FYI only USA, Russia, Japan, Germany, France are the major engine producers in the world be it military or civilian. For a country like India which didn’t have a huge manufacturing and high-tech industry like these nations it was a tough job even China failed in producing engines. But the development of the Kaveri engine isn’t complete failure it is being reported that the kaveri engine would be used to Power UAV and UCAVs. As Kaveri engine failed to power Tejas, Production aircraft will be powered by the GE F404-GE-IN20 turbofan engine, rated at 85kN with afterburn.
On 19 February 2015 at the Aero India 2015, Director of DRDO Dr. Tamilmani told reports that a tender of joint venture on development of the engine is issued with General Electric, Pratt & Whitney, Rolls Royce, Snecma, Eurojet, NPO Saturn, Klimov and IHI to use current engine technology by combining Kaveri engine technology with JV engine to produce an engine capable of producing thrust of 110-125 kN. Full development of the K 9 and K 10 engine would be completed by 2019 to power the indigenous twin engine AMCA.

Kalvari is going through its final phase of trials and we are hopeful that in July-August we will take delivery,” he said speaking to the media on the sidelines of a Navy-FICCI seminar on “Building India’s future Navy: technology imperatives.”
Six Scorpene submarines are being built under Project-75 by Mazgaon Docks Limited (MDL) with technology transfer from France.
On the recent decision by Sri Lanka to deny permission for a Chinese submarine to dock at Colombo, Adm Lanba said that it was a decision by the Sri Lankan Government.
“We have no dialogue on this with the Sri Lankans. It was a decision they have taken on their own,” he stated.
The decision by Sri Lanka came coincided with Prime Minister Narendra Modi’s decision to the Island nations. Chinese submarines on anti-piracy patrols had in the past docked.
Strategic Partnership ::
The Navy is hopeful of pushing the two deals under Strategic Partnership (SP) policy very soon given the high priority.
“As per the model, we all have to get the Acceptance of Necessity (AoN) on what we want to get the Strategic Partners build, so that the SP in each segment can be identified. We are hopeful that we will be able to move the process within six months,” Adm Lanba said.
Of the four segments under SP, two are for the Navy, submarines and Naval helicopters. The others are single engine fighter aircraft for the Indian Air Force and armoured vehicles for the Army.
Both the Navy deals have been held up from sometime due to delay in finalising the SP policy.
