Scottish Enterprise confirmed it did not receive a formal application for funding but did have informal discussions with Malin about the plans.
At the time, Scottish government policy guidance did not support the manufacture of munitions, and Malin was advised that any funding could only be considered if it aligned with government policy.
A spokesperson for Scottish Enterprise said: “We continue to work with the Scottish government as we implement the new policy.”
The Scottish government said it had provided more than £90m in funding to companies operating in the aerospace, defence and shipbuilding sectors since 2006/07.
“We continue to support the defence sector, particularly regarding workforce development, which is fundamental to our national security and a strategic driver for Scotland’s economy,” a spokesperson added.
