He was 78. A close friend of former President APJ Abdul Kalam, Verma had played an important role in the development of Light Combat Aircraft - Tejas.
He breathed his last at his residence in Laheriasarai, family and official sources said, adding that he was single.
During his presidential tenure, the "missile man" had twice visited Verma at his Darbhanga house and appreciated his efforts to popularise knowledge of science among masses.
Bihar Governor Phagu Chouhan and Chief Minister Nitish Kumar have expressed grief over Verma's demise.
