Carry On Constitution

The USS Constitution was one of ten Constitution Class Heavy Cruisers in the United System Space Navy. These ten Heavy Cruisers were all very old and had been decommissioned eighty years before, but because of the devastating losses during the System's war with the Zenites and the battle of Hell System Three, these decommissioned Heavy Cruisers were retrofitted, upgraded, and recommissioned. This was seen as the best and fastest way to rebuild the System Navy. As a consequence of the retrofits, upgrades, and innovations, these ten Constitution Class Heavy Cruisers were the most powerful ships in the System Navy.
The System Navy Chief of Naval Operation has tasked Fleet Admiral Timothy Holoran to command a fleet comprised of the ten Constitution Class Heavy Cruisers toward the center of the galaxy to attempt to discover why civilizations, peoples, and worlds beyond a point in the galaxy known a P-387 were utterly devoid of life.
The challenge was to speed to P-387 as quickly as possible to begin the investigation. This would take six months at ultra-light fourteen to get to their destination. On the way, we see the usual routine of the crew of the Constitution and those of the rest of the fleet.
Driving forward at ultra-light fourteen, they encounter a spaceship from another civilization and befriend their new acquaintances, who are challenged to undertake the mission of the United System Space Navy as allies.
Captain David Stevens discovered a powerful electromagnetic pulse that alters the subatomic structure of carbon and silicon making life impossible. Commissioned to discover the extent of the pulse, Captain Stevens and the Constitution with Captain John Self and the USS Constellation discover the pulse's path is an ever-widening circle which seems to have originated from the very center of the galaxy.
The challenge now is to discover the source of the death pulse and try to find a means of stopping the pulse from destroying any other worlds.
