Timeline of HAL Tejas - Wikipedia, the free encyclopedia
1969[edit]
- Indian government accepted the recommendation by its Aeronautics Committee that Hindustan Aeronautics Limited (HAL) should design and develop an advanced technology fighter aircraft around a proven engine
1970s[edit]
1975[edit]
- HAL completed design studies in 1975, but the project fell through due to inability to procure the selected "proven engine" from a foreign manufacturer and unfulfilled IAF requirements.
1980s[edit]
1983[edit]
- DRDO obtained permission to initiate a programme to design and develop a Light Combat Aircraft
1984[edit]
1985[edit]
- IAF submits Air Staff Requirements (ASR) for LCA in October 1985. This was initiated by the then Air Chief Marshal Idris Hassan Latif.
1986[edit]
- Government allocates 575 crores for the LCA programme.
- Programme to develop an indigenous powerplant (engine) was launched at GTRE.
1987[edit]
- Project definition commenced in October 1987 with French Dassault Aviation as consultants.
1988[edit]
- Project definition completed in September 1988.
1989[edit]
- Government review committee expresses confidence in LCA programme. It was decided that the programme will be carried out in two phases.
1990s[edit]
1990[edit]
- Design of LCA was finalised as a small delta winged relaxed static stability aircraft.
- Phase 1 of the development was commenced to create the proof of concept system. Financial problems within India prevented full scale operations from starting.
1993[edit]
- Full funding started from April 1993 full-scale development work for phase 1 started in June.
1995[edit]
- First technology demonstrator, TD-1, rolled out on 17 November 1995 and was followed by TD-2 in 1998. However, technical problems in flight control systems and structural deficiencies plagued the prototypes and they remained grounded.
1997[edit]
- Multi-Mode Radar (MMR) for LCA design work started at HAL’s Hyderabad division and the LRDE.
2000s[edit]
2001[edit]
- 4 May - LCA’s maiden flight successfully completed by Technology Demonstrator TD-1, on 2001. Prime minister Atal Bihari Vajpayee renames LCA as Tejas.
- Development assistance sought from Snecma on the Kaveri engine.[1]
2002[edit]
- 6 June - TD-2 makes a successful maiden flight.
- MMR system was reported to be not working as per the criteria laid down in requirements.
2003[edit]
- 25 November - PV-1 makes a successful maiden flight.
2005[edit]
- 1 December - PV-2 makes a successful maiden flight.
2006[edit]
- 13 May - The PV-2 went supersonic for the first time
- 14 May - The PV-2 went supersonic again, but this time in a weaponised state (i.e., carrying weapons such as missiles and an internal gun).
- 1 December - The PV-3 flew for the first time for 27 minutes at an altitude of 2.5 km and at a speed of Mach 0.8. The PV-3 was equipped with a more advanced pilot interface, refined avionics and higher control law capabilities compared with the previous versions.

Tejas PV-1 firing an
R-73 missile during weapons trials in Goa
- 25 April - The first Limited Series Production LCA (LSP-1) made its first flight and it reached a speed of Mach 1.1.
- PV-2 and PV-3 underwent sea-level trials at INS Rajali Naval Air Station, Arakkonam to study the effects of flying at sea-level, as all earlier trials have been conducted at Bangalore which is 3,000 feet (910 m) above sea-level.[2][3] The reliability of the LCA systems under the hot and humid conditions, as well as low level flight characteristics was tested.[4][5] It is due to this intense flight testing schedule that the LCA was not able to fly at the Paris air show-2007, as was originally planned.[6]

2010s[edit]
2010[edit]
- 23 April - LCA Tejas LSP-3 Makes Maiden Flight. LSP-3 is almost the final configuration including the new air-data computers, Hybrid Multi Mode Radar, new communication and navigation equipment and radar warning receiver. With this the LCA programme has completed 1350 test flights logging about 800 flying hours.[21]
- 2 June - LCA Tejas LSP-4 Makes Maiden Flight. The flight marks the first time for a Tejas aircraft flying in the configuration that will be finally delivered to the Indian Air Force.[22] In addition to the Hybrid MMR, the aircraft also flew with a functioning Countermeasure Dispensing System [23]

- 31 March 2013 - LSP 8 had a successful maiden test flight at Bangalore.[29]
- 28 Sep 2013 - The Light Combat Aircraft (LCA) Tejas successfully completed the maiden engine relight test on Friday -- a critical parameter the programme needs to achieve for the Initial Operational Clarence 2 (IOC-2).

Arjun (tank) - Wikipedia, the free encyclopedia
Planning and development[edit]
The DRDO, with its
Combat Vehicles Research and Development Establishment (CVRDE) as the main laboratory, was tasked to develop the hull, armour, turret, running gear and gun for the tank, with the powerpack being imported.
[18]
Although the development of the tank began in 1972 by the CVRDE, it was only in 1996 that the Indian government decided to mass-produce the tank at Indian Ordnance Factory's production facility in Avadi.
[11][19]
When first accepted for service in the army, the Arjun relied heavily on foreign components and technology. Initially close to 50% of the tank's components were imported, which included the engine, transmission, gun barrel, tracks, and fire control system.
[20] However, several of these have since been replaced by indigenous systems or are being supplied by Indian companies.
[21][22] Recent comments from Army sources indicate that the Russian T-90S will form the mainstay of its future force, despite that tank’s performance issues in hot weather.
The Arjun project experienced serious budget overruns and repeated delays that resulted in a development time of over 37 years. A complicating factor was that advances in technology and the threat environment in the intervening years led to multiple revision of requirements by the Army. While the government sanctioned
155 million (US$2.5 million) for the initial design in May 1974,
[18] by 1995, DRDO had spent
3 billion (US$48.0 million) on development due to changing requirements and inflationary cost increases

Arihant-class submarine - Wikipedia, the free encyclopedia
History[edit]
India continued to harbour deep ambivalence about nuclear weapons and did not accord a priority to their production until the 1970s. In December 1971, during the
Indo-Pakistani War of 1971, the
U.S. President Richard Nixon sent a
carrier battle group named
Task Force 74, led by the nuclear-powered
USS Enterprise, into the
Bay of Bengal in an attempt to intimidate India. In response, the Soviet Union sent a submarine armed with nuclear missiles from Vladivostok to trail the US task force.
[19] The salutary effect of the Soviet response demonstrated the deterrent significance of nuclear weapons and ballistic missile submarines to then Prime Minister
Indira Gandhi.
[20]Following the 1974
Smiling Buddha nuclear test, the Director of Marine Engineering (DME) at Naval Headquarters (NHQ) initiated a technical feasibility study for an indigenous nuclear propulsion system (Project 932).
[21]
The Indian Navy's
Advanced Technology Vessel (ATV) Project to design and construct a nuclear submarine took shape in the 1990s.
[22]First confirmation of the project came in 1998 from then
Defence Minister,
George Fernandes.
[23] The initial intent of the project was to design nuclear-powered fast attack submarines, though following
nuclear tests conducted by India in 1998 at
Pokhran Test Range and the Indian pledge of
no first use, the project was re-aligned towards the design of a ballistic missile submarine
[24] in order to complete India's
nuclear triad.
[25]
The ATV project overcame many challenges, the primary one being the design and miniaturization of the nuclear reactor.
[26] The lead vessel was first floated from its dry dock at a symbolic launch ceremony on 26 July 2009.
[27]
