Lockheed Martin Statement on AETP Technologies and F-35StatementWe stand ready to support and continue to work with the U.S. government on the capability and performance upgrades that best support their requirements for the F-35 for decades to come– including an engine upgrade. AETP technologies deliver more power and greater cooling capability, which is required as we modernize the F-35 beyond Block 4. Lockheed Martin’s top priority remains meeting the needs of our service men and women. To ensure our customers stay ahead of emerging threats, the F-35 will need even greater capability, readiness, range and thrust, which will require an upgraded engine. In Lockheed Martin’s assessment, Pratt & Whitney and GE have AETP technology options.
