A-65A "Hazard" Tilt-Wing SSTO (top) and A-65B "Danger" Tilt-Wing SSTO (bottom).
I've put in quite a lot of effort into the designs of these craft, with what I think is a perfect balance between efficiency and aesthetics.
The A variant uses 2 Kodiak engines for RATO VTOL, resulting in a lower dry mass and greater efficiency. Based on the multiple times I've flown this craft, it averages around 5.4km/s-5.4km/s of deltaV in LKO, enough to land anywhere except for Eve and Tylo.
The B variant relies on raw jet power to VTOL, using 4 Panther engines alongside the 4 RAPIERs and 2 Whiplashs. Because of the super high stationary TWR, it is a lot easier to fly compared to the A variant, though it suffers from slightly lower vacuum TWR and a less than aesthetically pleasing engine array. It averages around 4.9km/s-5km/s of deltaV in LKO, once again enough to land everywhere except for Eve and Tylo.
Both can however, perform a round trip to Laythe with no mining/refueling, which was my original intent when making these crafts.
