 Doug Drexler had intended for Enterprise to undergo a major refit if a fifth season had been produced , and the series had not been cancelled at the end of the fourth season . This would have seen the addition of a secondary hull , and resulted in the ship taking on an appearance closer to the vessels in The Original Series and later series . The redesign made its debut in the 2011 edition of the official Ships of the Line calendar . It was one of two designs for vessels never seen on screen to appear in that year 's calendar , with Matt Jefferies ' design for the USS Enterprise ( XCV @-@ 330 ) also appearing .
