USS Endeavour ( NCC - 71805 ) The USS " Endeavour " ( NCC - 71805 ) was a 24th century Federation starship operated by Starfleet In 2368 , the " Endeavour " joined Captain Picard ' s fleet that blockade d the Klingon - Romulan border during the Klingon Civil War . The ship was one of twenty - three assembled for the fleet and was one of the seventeen chosen for the tachyon network . Identified by its name and registry number , the ship ' s position in the network was monitored from the . When the network was disrupted by a high - energy burst released by the Romulan s , the net was no longer effective in a of ten million kilometer s around the . Subsequently , Picard ordered the fleet to proceed to Gamma Eridon at maximum warp , where the fleet would attempt to reestablish the net before the Romulans got there . ( ) Later that year , the ship was on a mission in the Cleon system . ( ) Captain Amasov of the " Endeavour " was involved in a conflict with the Borg sometime prior to 2371 . After the encounter , Amasov reflected , " " . . . It is my opinion that the Borg are as close to pure evil as any race we ' ve ever encountered . " " ( ) In 2373 , the " Endeavour " again faced the Borg at the Battle of Sector 001 . ( ) Appendices . Background information . The " Endeavour " was identified as a starship in the . On the same page , there was a starboard profile view of the " Endeavour " . According to the authors of this reference work , the " Endeavour " " " was named in honor of British explorer ' s flagship and for NASA ' s space shuttle . " " The further stated , " " The " Endeavour " appears to have been the sole survivor of the battle of Wolf 359 , although this was not explicitly established in any episode . We know that the " Endeavour " was still around in 2373 because it was part of the armada that met the Borg in " Star Trek : First Contact " . Nevertheless , Amasov ' s first - hand experiences with the Borg ( from which Janeway read in " Scorpion , Part I " ) had to have been recorded before the " Voyager " departed from Deep Space 9 in 2371 , which was before the Borg battle in " Star Trek : First Contact " . It therefore seems likely that the " Endeavour " ( and Amasov ) were also at Wolf 359 in 2367 . " " In a preliminary draft for , dated 29 September 1995 , an " Endeavor " was explicitly named as one of the starships engaged in the Battle of Sector 001 in , " " PICARD : Signal the " Endeavor " to fall back . We ' ll cover them . " " , and 11 , " " The " Endeavor " moves off as the Borg FIRE at the " Enterprise " and BLASTS the saucer section . " " These references did not make it into the final cut , leaving the one " Nebula " - class vessel actually seen , unnamed . Production Illustrator John Eaves though , had worked on 6 September on a preliminary design for an " Endeavor " , albeit of an entirely different configuration , with " Nebula " - , and traits . As he recalled , " " In the early script there had been a ship called the " Endeavour " that used to play quite a big role . I was drawing that and the E at the same time . They were kind of similar shapes , so it was almost a way of trying things out . I thought , ' If I want to see this on the E , let me try it on the " Endeavour " sketches first . ' I ' d mess around with the body , tapering it to the nacelles in one sweepy part , things like that . It was definitely an idea platform for me . So , at this point I just put " Enterprise " on all the " Endeavour " sketches , because by that time " Endeavour " was gone and nobody had ever seen them ! " " ( )
