The Ingram-class Space control ship was a class of United Federation of Planets starship active in the last quarter of the 23rd century. The original class ship, USS Ingram, was constructed in the early 2280s and was a competing design - alongside the USS Excelsior, in the transwarp drive system project. After unsuccessful trials, its propulsion systems were swapped for conventional (LN-72) warp drive nacelles and funding for the remaining vessels was cut . However several years later, changes in policy would see funding restored and several other vessels were built to the same specifications (Simonov, Richmond, Resource and Patriot) , with the class being confirmed in name as Ingram.
