As TommyT, post #2 alludes. Certainly no more weird than the age old tradition of naming boats, usually femine names at that.
Airforce guys name their bombers. At least they did, especially when bombing. Hmmm, not so much fighters.
That has the same feel as naming a chopper or a dragracer, but seldom a roadracer. The first are more personal. The latter less so.
