There are 5 main versions of the Gepard (1 to 5), plus sub versions such as 3.9 (Vietnam), 5.1, 5.3, etc. Some versions have hangars, some not. Version 3 has hangar, the thing is, when I see the Gepard pic with the hello, I just don't see how the full length of the hello can fit there.
The two upcoming Gepards for Vietnam seem to be the version 5.3, also with hangar.
I just don't see why they don't continue the triangular space all the way for extra protected space, I don't see the point of having it open like that. This is intriguing.
Yes, it makes sense that need to have a full hangar for an ASW hello.
