New Delhi: Air Chief Marshal Amarpreet Singh on Thursday raised concerns over the failure of government defence manufacturing companies to meet delivery deadlines.
Speaking at the CII Summit 2025 in New Delhi, the Chief of Air Staff said, “Timeline is a big issue. So, once a timeline is given, not a single project that I can think of has been completed on time. So this is something we have to look at. Why should we promise something which cannot be achieved? While signing the contract itself, sometimes we are sure that it is not going to come up, but we just sign the contract.”
“Why should we promise something which cannot be achieved?” he added.
This is not the first time Air Chief Marshal Singh has flagged the issue. Earlier in February this year, during Aero India 2025, the Chief of Air Staff pulled up Hindustan Aeronautics Limited (HAL) officials over the delay in the delivery of the Light Combat Aircraft (LCA) Tejas Mk 1A.

“I can only tell you our requirements and what our worries are. You have to alleviate those worries and make us more confident. At the moment, I am just not confident of HAL, which is a very wrong thing to happen,” Air Chief Marshal Singh had told the HAL officials.
