How many pieces did LEGO set 75159 Death Star contain when released in 2016?

LEGO set 75159 Death Star contained 4,016 pieces when it was released in 2016.

Set 75159 is a large LEGO Star Wars playset depicting the Death Star battle station. It was released in 2016 as a successor to the earlier 10188 Death Star, retaining the concept of a large, openable playset filled with rooms, figures, and movie scenes.

The set included minifigures and locations associated with both the original Death Star and the second station shown in Return of the Jedi. Its interior-focused design allowed builders to display scenes such as the detention block, the trash compactor, the throne room, and Darth Vader’s meditation chamber.

Collectors sometimes confuse 75159 with 10188 because both sets share the Death Star name and a broadly similar layout. The earlier 10188 set contained 3,803 pieces, while the 2016 successor increased the count to 4,016. Neither should be confused with the much larger UCS Millennium Falcon.
