De ce

Aflam lucruri noi, pentru noi, despre UH-1Y:

“The IDAS (Improved Defensive Armament Subsystem) is rated for a 1,000-pound payload; however, the IDAS mounting lugs on the airframe are limited to a weight of 571 pounds. The mounting lug weight limitation inhibited flexibility in configuring mission weapon load outs and did not allow the users to realize the full capability of the IDAS.

For example, during the Offensive Air Support (OAS) missions, the UH-1Y had the power to lift two fully loaded 19-shot rocket pods. The IDAS mounting lug weight limitation restricted the pods to only 11 rockets a piece. If the mounting lugs could support the full capability of the IDAS an additional 16 rockets could be carried, resulting in an increase of firepower from 22 to 38 rockets which would lead to improved support of the Marine on the ground. The IDAS weight limitation also affected the use of external auxiliary fuel tanks. Because of the IDAS mounting lug weight limitation, the 77-gallon tank could not be fully fueled and, therefore, yielded only 4 to 17 minutes more on-station time than internal tanks alone.”

“The small amount of on-station time gained did not offset the loss of weapons stations. Additionally, the external tanks severely reduced the forward and aft depression limits of the crew served weapons and created an obstacle for troops entering and exiting the cabin for assault support missions where troops needed to exit and enter the cabin rapidly. The overall effect was that flexibility was lost during mission planning and mission execution.”
