SIEPU modifications optimize the aircraft to improve mission capabilities
The first Bell AH-1Z set to receive the Structural Improvement Electrical Power Upgrade (SIEPU) modification to be provided by Bell Textron, a Textron Inc company, under a contract with the U.S. Marine Corps, has arrived at Bell’s Amarillo Assembly Centre, according to a press communique.
SIEPU modifications optimize the aircraft to improve mission capabilities, aircrew safety, and interoperability by increasing the electrical power capacity on the aircraft and support the integration of additional cabin capabilities
“The Bell AH-1Z Viper and UH-1Y Venom provide the backbone of attack and utility aviation support in the various battlespaces in which they are used, so SIEPU comes at an important time for the future strategic implementation of this platform,” affirmed Mike Deslatte, Bell H-1 Senior Vice President and Programme Director.
With SIEPU, H-1s will be able to upgrade to current weapons systems with next generation capabilities, including kinetic long-range munitions and air launched effects as well as new non-kinetic capabilities. These upgrades extend reach and range while simultaneously enhancing standoff distance.
“We are confident that SIEPU will help the Marine Corps expand mission essential tasks with more mission flexibility,” asserted Danielle Markham, SIEPU Programme Manager.
Prior to arriving at the Bell Amarillo Assembly Center, the AH-1Z and UH-1Y completed datalink capabilities testing with the Marine Corps modifications at Camp Pendleton and testing with VMX-1 in Yuma. Bell plans to continue supporting the AH-1Z Viper and UH-1Y Venom through the 2040s in alignment with the Marine Corps Aviation Plan.
