A mod aircraft called [Viper II]. Built with [82] of the finest parts, its root part is [Inline Cockpit].

Built in the [Spaceplane Hanger] in KSP version [1.04]. This is a replica of a Colonial Viper from Battlestar Galactica. I did not attempt to make any specific version. It’s not fully a Mk 1 from the 1978 version or the Mk II from NuBSG. (Though I did get more of my inspiration from the latter)

Recommended ascent Profile:

It is capable of getting to low orbit from the runway - though it needs the help of a little extra fuel tankage in the form of a drop tank to do so. Recommend 45 degree ascent until just after 10,000 meters, when you’ll have drained the drop tank and released it.

Then slowly drop the nose to between 20-25 degrees until about 15,000 meters, then further to 10-15 degrees between 15,000 and 20,000 meters altitude. Then keep flying until around 25,000 meters altitude. Watch the speed carefully at that point. As soon as the speed levels off and begins dropping, angle the nose up to between 20-25 degrees pitch and switch the engines to rocket mode.

At between 65-67,000 apoapsis, throttle the engines down to zero with the X key (you’ll go over the 70,000 meter level before they shut off completely), pitch the vehicle to pure pro-grade attitude, turn on the RCS thrusters and thrust forward with those to keep your apoapsis from dropping (hey - you may as well burn off some extra weight that’s NOT your main fuel supply).

Circularize at apoapsis and you should have a small amount of fuel remaining to rendezvous with a tanker or carrier in orbit to top off the tanks (you DID plan to rendezvous with a larger craft didn’t you? :D ) If not, you should have enough fuel/oxidizer left to de-orbit and land.

If all else fails and you find yourself stuck in a decaying orbit or out of fuel in deep space, there is a failsafe in the form of an Ion Engine tucked between the three main engines and solar panels on the bottom of the craft! If you’re truly confident in your abilities, then you may want to pull those to save a little weight. But hey - you never know when you might need it…

In terms of performance, it’s not the greatest turner in atmosphere. Any atmospheric fighter will likely wax it’s tail. But in space, it’s VERY snappy and maneuverable! These are the compromises you’ll always see when trying to make a space fighter like this with no cheats. But I believe I’ve actually made a craft that’s both a good replica of an icon AND a decent aero-space fighter as well! So I’m fairly pleased with it!
