Interested when they announced the mustang but didn't know what variants would be available? In the release about AC 1.0 they also now have 4 different mustang standalone ships available. At present there are not specs but there are descriptions to give an idea of roles. I will summarise and link to each ship. Note: all ships include SelfLand hangar and 6 months insurance. First off the mustang alpha, base ship - $30 It is light and reasonably quick. Likely to not take much of a beating though and may develop issues if pushed too hard. Has optional cargo capacity addon: https://robertsspaceindustries.com/pledge/Standalone-Ships/Mustang-Alpha The Mustang Beta, explorer - $40 This is the exploration variant. Has a different engine equipped to enable long distance travel and higher quality interior for comfort. https://robertsspaceindustries.com/pledge/Standalone-Ships/Mustang-Beta The Mustang Gamma, racer - $55 This version of the mustang has had engine parts replaced by variants designed for faster speed and acceleration. The original racer, the mustang omega is no longer available for pledging. https://robertsspaceindustries.com/pledge/Standalone-Ships/Mustang-Gamma The Mustang Delta, fighter class - $65 This has replaced the standard hull with strong lightweight armor. It has a lower signature to other vessels as a result. This should make the mustang nimble and harder to find to make up for having less armor and armament than other military class fighters. No details whether it will be tougher than other variants. https://robertsspaceindustries.com/pledge/Standalone-Ships/Mustang-Delta
