The Cowboys flew old Lightnings before The War began. They were the first successful multi-role attack craft of the gravtech era. Their nose-mounted main cannon could penetrate almost any armor, and the four hardpoints carried anything from ground-targeting bombs to anti-ship rockets. They were an effective fighter/attack craft for their time, but they were nearly a century old when The War came upon us all. Most had been retired and long since sold off to corporate or system militias. Or subnational states like the Republic of Texas. War-era anti-ship torpedoes and other upgrades made them effective once more, but we had already upgraded to the Avengers. I have always been pleased with that upgrade.
