Thank you for the comment! I see your concern but allow me to explain. This might be an optical illusion.
The Raptor-class is about 600m long, and the hangar deck makes up about a sixth of its length, so that's about 100m long and about 60m wide. I also picture landing ships not coming in at full throttle so the length shouldn't be much of a problem.
As a comparison, the Patriot on the right, is about half the Raptor's size. Its hangar pods can only hold up to two fighters each, while the Raptor's is large enough to hold about half a squadron. The Raptor is not a carrior, therfore what fighters it carries are only for superiority in addition to its own heavy weapons.
Honestly speaking, the Raptor was in fact one of the earliest models I made. Looking at how my ships developed since then I probably wouldn't make such designs anymore, as its almost skeletal shape with a large forward facing hangar does pose quite some tactical risks.
