Comments: The F-6 Wyvern is the standard gunship of the Neubayern Army.  It
entered service in 5618, and has been used in several recent conflicts.
The Wyvern's mission is primarily to engage ground targets and provide
close air support for friendly troops. It is also good at air superiority
missions, although this role is usually left to aerospace fighters.

Wyvern pilots have a huge missile load at their disposal, and are taught
to use it extravagantly. When engaging enemy aircraft, Wyverns generally
fire a dozen or more air-to-air missiles to keep the enemy busy while the
Wyvern maneuvers in for the kill. If the enemy aircraft tries to return
the favor, the Wyvern's 30mm cannon is equipped for point-defense fire.

Design Notes: Designing a useful turret gun for this gunship turned out
to be a major headache. None of the design sequences in FF&S produced a
totally satisfactory gun--the high energy weapon sequence was especially
bad. To get the 30mm gun here, I designed a mass driver 'by the book' and
multiplied its range by 10 and its damage by 3.

Does anyone have any idea why the book design sequence gives a 30mm
cannon with a muzzle velocity of 6000m/s good penetration, but less
damage and range than a .50 M2HB machinegun?
