ABSI Aerospace & Defense was founded with the goal of delivering rapidly executable acquisition options to assist acquisition managers in supplying the warfighter with critical UAS technologies and training. We understand the challenges created by the rapid requirements tempo and the extended procurement process. And we know that non-program funding that expires rapidly and is nearly impossible to execute doesn't just put programs at risk... It puts lives at risk. 

We understand the problem because it was our problem too. And we formed ABSI Aerospace & Defense because we are passionate about providing a solution.
