CEDAR RAPIDS, Iowa. Collins Aerospace, a unit of Raytheon Technologies Corp., announced that it has begun shipping parts following a second multi-year contract it received in November to supply Northrop Grumman with NP2000 propeller systems for 39 E-2D aircraft.

The NP2000 propeller and digital Electronic Propeller Control System is designed to provide E-2D Advanced Hawkeye operators with reduced maintenance time and cost, and enhanced crew comfort and safety. 

According to the company, NP2000 offers operators the ability to replace individual blades on-wing for reduced maintenance time and increased aircraft availability. By improving speed holding and blade synchronization, NP2000’s digital Electronic Propeller Control System also enhances crew comfort and safety by reducing vibration and noise inside the cockpit.

NP2000 has been in service with the U.S. Navy and international customers on the Northrop Grumman E-2 and C-2 since 2004, and with the U.S. Navy and U.S. Air Force on Lockheed Martin C-130 variants since 2008. Over that time, the company claims that the NP2000 has accumulated over 1 million flight hours.
