SH 20
RETRACTABLE DOOR MOUNTING FOR HELICOPTERS
MISSION
The SH 20 door mounting is designed
to provide multi-mission and multi-role
helicopters with air-to-ground fire-support
capability. The use of this mounting is
particularly suitable for missions such as
surveillance or stealth target approach
(armament not visible when door is closed)
and C-SAR.
The retractability of the mounting allows
access to the cabin completely cleared during
loading/unloading operations. The SH 20
uses the 20 M 621 cannon well known for its simplicity (operation and maintenance) and firing
the wide spread NATO-standard 20mm x 102 ammunition. The SH 20 can be fitted to new or
retrofitted helicopters. Its light weight and low bulk do not impair the aircraft’s capabilities.
