No, each warehouse only has 50 storage spaces. But at the initial base there are 3 hangars, in which there are 5 more places. That’s why it comes out to 65 (50+5*3). In hangars, not in a warehouse. Build a base with only one warehouse and no hangars (or dismantle all the hangars at the starting base) and you will get 50 storage spaces and no more. Hangars provide the supplement, and there cannot be too many of them at bases.
