Pratt & Whitney, a division of RTX, has secured a substantial contract worth up to $1.3 billion to enhance the F135 engine core of the F-35 Lightning II. The upgrade, known as the Engine Core Upgrade (ECU), is designed to bolster the engine’s durability while improving power and cooling capabilities for the Block 4 and future variants of the F-35. This contract signifies a major step forward in Pratt & Whitney’s efforts in risk reduction, design maturation, aircraft integration, and mobilizing the supply base for ensuing production. The collaboration between Pratt & Whitney and the F-35 Joint Program Office was recently reinforced through the successful completion of a preliminary design review this past July, indicating a strong alignment between the two entities.
The F135 program is not only a technological marvel but also a significant economic driver, particularly in states like Connecticut and Maine. It supports over 57,000 jobs across 43 different states, making it an essential contributor to local economies. To date, more than 1,200 F135 engines have been delivered, accumulating over 900,000 flight hours. The ECU is set to be incorporated into new F-35s during production or retrofitted at various sustainment facilities around the globe, benefiting all operators of the F-35 aircraft and ensuring they have access to the latest advancements in engine technology.
The consistent success of Pratt & Whitney in the F135 program can be largely attributed to robust bipartisan and bicameral support from Congress. Key figures like Sen. Susan Collins and Rep. Rosa DeLauro, who are senior appropriators, have championed the importance of this program. Their backing ensures that the F135 engine will continue to deliver essential capabilities for years to come. This level of support highlights Pratt & Whitney’s unwavering dedication to improving the F-35’s operational efficiency while also securing significant economic advantages for numerous states across the nation.
In conclusion, the $1.3 billion contract for the F135 engine core upgrade stands as a testament to Pratt & Whitney’s vital role in elevating the performance of the F-35 Lightning II. Driven by strong bipartisan support and notable economic relevance, the contract is set to facilitate risk reduction, enhance design capabilities, and prepare the supply chain to meet future production demands. This unified endeavor aims to ensure the F-35 continues to excel in its operational role globally, reflecting Pratt & Whitney’s commitment to advancing military aviation technology.
