Probably, all of the ammunition that has not been shared to media yet, covered with a single cover. There are many mockups behind that covering. However, Gezgin's silhuette is obvious.One of them is high likely Gezgin but I am not sure about other missiles. Siper or Akdoğan (?) or both of them under the same cover ?
Some old projects such as cluster bomb and Toros MLRS rocket can also be seen in the background.
Anyone have guess?
The nose cone section which is the most visible silhouette of what's underneath the apron, still must be something closer to an surface-to-air missile - SM-3 seems to fit best.
