Trishul (IAST: triśūla "Trident") is a low-level quick-reaction short range surface-to-air missile developed in India by Defence Research and Development Organisation (DRDO) as part of the Integrated Guided Missile Development Program (IGMDP). It can also be used as an anti-sea skimmer from naval ship against low flying missile, attack helicopter and aircraft.[4][5]

History and development

The Trishul missile project was commissioned in 1983 as a part of Integrated Guided Missile Development Program. In 1985, Trishul made its first unguided flight from Satish Dhawan Space Centre, Sriharikota.[6] The missile made its first full range guided flight in 1989. By the late 1990's, DRDO pushed Trishul as an alternative to Barak 1 for Indian Navy.[7] The project was planned to be completed by 1992 and to be fitted in Brahmaputra-class frigates as an anti-sea skimmer. In 1992, the missile was successfully tested against a target and reached Mach 2 speed. In 1997, the associated radar systems for detecting the incoming sea-skimmer were operational, but Indian Navy expressed its displeasure in the developmental delay of Trishul for the Brahmaputra-class frigates and finally opted for Barak 1. The launch system was developed by Bharat Dynamics Limited in 1998.[8]

As of 1998, the missile had undergone over 24 flight trials and the missile was inducted into service by Indian Army and Indian Air Force (IAF) in 1999.[9] Upon reviewed by DRDO in October 2001, the missile system was found deficient as the tracking radar beam was getting intermittent breaks resulting in the missile missing the target and the heavy BMP-2 chassis did not meet the Army Qualitative Requirements (AQRs) for mobility.[10] On 25 January 2002, the naval variant of Trishul was test fired in sea-skimming mode from INS Dronacharya.[11] In 2003, Government of India announced that the missile will be a technology demonstrator and de-linked it from Integrated Guided Missile Development Programme.[12] But Ministry of Defence (MoD) was not interested in downgrading the Trishul Missile project. After modification in guidance, sub-systems and propellant composition, four missiles in full combat configuration was launched from BMP-2 from June 22 to June 25, 2003. The test achieved miss distance against moving targets above the specified requirement of the Indian Armed Forces. All the sub-systems, air frames, controls, integrated with ground control system of the combat vehicle worked well.[13] By this time Trishul became more of a research and development oriented project instead of an user driven one backed by the armed forces.[4]

Trishul was successfully test fired from Integrated Test Range (ITR) on 10 February 2004.[14] On 5 October 2005, Trishul fired towards the sea from ITR was able to hit a pilot-less target aircraft.[15] Till October 2006, 80 flight tests were already completed and DRDO was in dialogue with the IAF for user trials and induction.[5][16] Due to project delays and modification of Qualitative Requirements (QRs) and operational requirements over time, Trishul is no longer able to meet the need of the users. For continuation of the project and funding, it was proposed that the missile will be deployed in certain locations to conduct training, fire control and air defence practice. As per Ministry of Defence (MoD), Trishul met the performance parameters set by the original QRs but failed to achieved the perfect three-beam guidance and developing the millimeter-wave active radar homing seeker.[17] In 2008, Minister of Defence A. K. Antony officially announced the closure of the programme on a written reply to Rajya Sabha. The development cost of the programme was 2.826 billion (US$33 million).[18] The team behind Trishul was reassigned for the development of Barak 8, a joint project between DRDO and Israel Aerospace Industries (IAI).[16]

Characteristics

Trishul had a range between 300 m (980 ft) to 9 km (5.6 mi).[14] DRDO also made an enhanced 11 km (6.8 mi) range variant for the Indian Air Force.[16] It is powered by a Dual-thrust propulsion stage using high-energy solid propellant.[2] Trishul weighs 130 kg (290 lb) and is capable of carrying a 15 kg (33 lb) warhead. Trishul is 3 m in length and 200 cm in diameter. The modified naval variant use command to line-Of-sight guidance mechanism. The missile can be employed against Sea skimmers with a fire control radar. Trishul flies at supersonic speed. It has a low altitude radio altimeter and height lock loop control.[15]
