The Air Force has been burning the midnight oil, answering questions from Boeing and Northrop Grumman about its tanker requirements.

This week, the Pentagon has posted roughly 80 pages worth of responses to comments and questions by the two lead competitors for the lucrative contract.

The Air Force had planned to release its final tanker requirements as early as the end of November, though the Pentagon’s chief weapons buyer wouldn’t commit to that date earlier this week.

The Air Force has been responding steadily to the queries by Boeing and Northrop since releasing the draft requirements in late September. The agency hopes to award the contract next summer.
