Abstract	A top level review of major Navy aircraft acquisition programs was given. The EA-18G variant of the F/A-18E/F Super Hornet will be replacing the EA-6B as the front line carrier based electronic warfare platform. The EA-18G will use the same flight control hardware as the Super Hornet. Flight Control Computer software is being updated to modify air data position error corrections for new antennas and improve some built-in-test capabilities. The EA-18G Growler will enter initial fleet operational capability in 2009. The first F-35 Joint Strike Fighter prototype has flown seven times since 15 Dec 2006. So far, flight control systems including the primary flight control surface electrohydrostatic actuators have performed well. Some adjustments to air data probe corrections were found to be necessary after the first flight. The V-22 tilt rotor has completed Operational Evaluation by the Marine Corp and will enter operational service in the summer of 2007. The Air Force variant of the V-22 will go into operational evaluation in the 3rd quarter of 2007 and operational service in early 2009. The Navy is working on a new version of the carrier based airborne early warning aircraft. The new E-3D advanced Hawkeye will have some small improvements to its current mechanical and electronic flight controls. First flight is planned for August 2007. A new Heavy Lift Replacement helicopter, the CH-53K, has started initial development. The CH-53K will have a fly-by-wire flight control system incorporating rate command/attitude hold and attitude command/velocity hold control laws. It will also have the capability for automatic approach to hover, landing, departure and wave-off. The contract was awarded to Sikorsky in April 2006. The new P-8A Multi-Mission Maritime Aircraft will be replacing the aging P-3 Orion. The P-8A will be based on the proven Boeing 737-800 platform, modified to meet the mission requirements. The electronic flight control system will use the same hardware as the current 737 but have new control laws and autopilot modes to address the Navy mission. In the UAV arena, the MQ-8B Fire Scout reconnaissance helicopter had its first flight in December 2006. It incorporates a new 4-bladed rotor, increased fuel capacity and a greater payload volume. It will enter operational service on Littoral Combat Ships in late 2008. The Broad Area Maritime Surveillance (BAMS) UAV is at the RFP evaluation phase with contract award anticipated this fall. The BAMS will provide persistent maritime intelligence, surveillance and reconnaissance. UCAS-D is the Navy’s current thrust into carrier based unmanned tactical aircraft. UCAS-D is focused at demonstrating key technologies for carrier suitability. Contract award is anticipated sometime this summer. UCAS-D is a precursor to an eventual competitive procurement for an operational vehicle. Although the EA-18G will be replacing the EA-6B, the EA-6B will remain in operational service for some time. The electronic flight controls have been upgraded with new hardware and software. Operational Test is complete and the new system is being installed in fleet aircraft. Finally, NAVAIR’s Terrain Avoidance Warning System/Ground Proximity Warning System was described. This digital terrain map based system is fielded in the F/A-18C through F aircraft and the AV-8B. Its is being tested for EA-6B, MH-80R/S, T-45 and E-2D and being tailored for AH/UH-1Y/Z and CH-53K. The system has two documented “saves.” and is responsible for a statistically significant reduction in Controlled Flight Into Terrain mishaps. The program received the FAA’s 2006 Excellence in Aviation Research Award.
