Avik: Flamethowers seem to be a part of the Indian Army inventory.
4.5 Flame throwers
To meet urgent requirement of the weapon for operations, Army HQ proposed in June 1999 procurement of 600 disposable flame throwers. The proposal also indicated that 600 more flame throwers were required under the ninth Army plan.
In response to Ministry’s enquiries KBP Tula Russia offered (June 1999) to supply the weapon at unit rate of US $ 3600 for an order of 600 throwers and at the rate of US $ 3500 for an order of 1200 numbers.
Ministry urgently concluded a contract in June 1999 for 1200 flame throwers at US $ 3500 each with delivery schedule in two lots of 600 pieces each aggregating US $ 4.2 million equivalent to Rs 18.22 crore by two months from the date of signing of the contract.
Audit scrutiny revealed that a delegation of the Army witnessed a live demonstration of the weapon conducted by the firm as early as in September 1995. In its evaluation report, the delegation had observed, among other things, that target engagement could not be analysed beyond 350 metres vis a vis the 1000 metres range claimed by the firm in its technical offer, the firing could be conducted only during day light as no night-sight device was developed and “the terminal effect could not also be assessed as there was no incendiary effect”. The Scientific Adviser to RM had also brought to the notice of the Defence Secretary ( November 1995) that the DRDO representative in the delegation had reported that during the demonstration of September 1995, 14 weapons were fired at a range of 200 metres and none of the shots hit the targets at that range. However, the delegation recommended procurement of the weapon only as a one time buy, suggesting future requirement be met from indigenous source by its development and production. Accordingly 300 flame throwers were procured in September 1996 as a one time buy.
Against these recommendations of the delegation, the Ministry at the instance of Army Headquarters decided to go ahead with further procurement of flame throwers at a total cost of Rs 18.22 crore even though it did not meet operational requirement. The delivery commenced only after August 1999 thereby being non - available during the operation.
Here is a report of a relatively recent use (2001)
