Star Trek: The Official Starships Collection - Klingon D7-Class Battle Cruiser
Star Trek the Official Starships Collection Part 67 features the Klingon D7, a warship that first appeared in the Star Trek: TOS episode 'Elaan of Troyius'.
The D7 class posed serious problems to the security of the Federation throughout the 2270s. This was at a time when there was a ‘cold war’ between the two powers, which had been going on since at least 2223. The magazine looks art the capabilities of this warship and its design by Matt Jefferies.
