Amid all its upgrades and advances, the US Navy’s newest aircraft carrier, the USS Gerald R. Ford, is lacking one feature: urinals.

Every bathroom on the Ford is, for the first time, gender-neutral, equipped with flush toilets and stalls, according to Navy Times.

Bathroom-design experts have said sit-down toilets are less sanitary and take up more space, and most of the Ford’s crew members are men. (Women are only about 18% of the Navy.)

But the Navy has said getting rid of urinals has advantages for current and future operations.
