The Pegasus is the most versatile single seat fighter/scout rocket money can buy. Whatever your need, scramble interceptions, orbital superiority, combat space patrol, front line or remote support, or long range scouting, the Pegasus can provide, and is the market leader in several of those niches.
It's sealed gas core nuclear pile is maintenance free, and only needs to be refueled once a year, under normal use (please use a certified Class A starbase). It uses liquid hydrogen for propulsion mass, and with it's internal filters, even lightly refined l-hyde will get it moving (continued use of lightly refined l-hyde may void warranty). It mounts a penetrating axial laser, and comes with a dorsal hardpoint, mounting standard rapid fire lasers. And, it can land anywhere, no infrastucture needed for pilot mounting and unmounting.
The high efficiency gas core nuclear rocket is good for 6 g acceleration (using standard refined l-hyde), and the padded gee-couch will make if feel like 4. The integrated thermopile system allows plenty of electricity, as long as your pile remains hot. The copious internal l-hyde tanks provide enough delta-vee to reach the Moon from Earth, and return (optional inflight refueling kits are available). A pilot can go from ready room to LEO in less than five minutes.
With it's speed, the Pegasus can be the first to the fight. With it's arms, it will be the last to leave the fight. It's main armanent is a centrally mounted pulse laser cannon, the integrated cooling fins can be seen on top of the Pegasus. Just a few pulses can punch through any armor. But that's not all. The Pegasus has a dorsal hardpoint, typically mounted with a rapid fire anti-missile/strafing laser (as seen in the images), but it can also mount missiles, a torpedo or other weapons.
Finally, the Pegasus is rugged enough for any theater. As you can see, with it's integrated ladder, the pilot can mount and unmount unassisted. Refueling and minor maintenance tasks can be performed by even the least mechinically skilled pilots. You can park a squadron on a minor asteroid and they can patrol for a year!
