BETHESDA-<\/strong> Lockheed Martin<\/a> Aeronautics has received a $18,789,801 contract modification to develop and integrate an F-35 Lightning II<\/a> variant tailored to an unnamed foreign military customer.<\/p>\n\n\n\n

The U.S. Department of War announced the award on October 15, 2026. The foreign government is funding the full amount, and the work is scheduled to continue through December 2030.<\/p>\n\n\n\n

New Contract Extends Country-Specific F-35 Development<\/h2>\n\n\n\n

The latest award adds work to an existing contract for the development, demonstration and integration of an F-35 variant designed around a foreign customer’s requirements. The Pentagon has not disclosed the country’s identity or the specific technical changes planned for the aircraft.<\/p>\n\n\n\n

The modification, designated P00011, applies to contract N0001922C0015 and combines cost-plus-incentive-fee and firm-fixed-price terms.<\/p>\n\n\n\n

The entire $18,789,801 was obligated when the modification was awarded. The contract was not competitively procured, and Naval Air Systems Command (NAVAIR) at Patuxent River, Maryland, is the contracting activity.<\/p>\n\n\n\n

The award continues an established development effort rather than announcing a separate aircraft purchase. The available contract details do not specify the number of aircraft associated with the modification.<\/p>\n\n\n\n

Approximately 80% of the work will take place in Fort Worth, Texas, where Lockheed Martin manufactures the F-35. The remaining 20% will be performed at undisclosed locations within the continental United States.<\/p>\n\n\n\n

The work is expected to finish in December 2030. The extended schedule allows the contractor to continue the system development, demonstration and integration activities covered by the modification.<\/p>\n\n\n\n

The customer is paying for the full scope of this contract action through the US Foreign Military Sales (FMS) program. FMS is a government-to-government mechanism through which the United States provides approved foreign customers with defense equipment and related services.<\/p>\n\n\n\n

Earlier Contract Modifications Funded Similar Work<\/h2>\n\n\n\n

The latest award follows earlier modifications supporting the development of a customized Joint Strike Fighter variant.<\/p>\n\n\n\n

In August 2022, the US Navy<\/a> awarded Lockheed Martin a $53.4 million contract modification for continued engineering work on the design and development of an F-35 variant tailored to an unspecified FMS customer.<\/p>\n\n\n\n

In August 2025, the Navy awarded another modification worth $12.9 million for the same broader development effort. The latest $18.8 million action continues that work and extends the program’s engineering timeline through December 2030.<\/p>\n\n\n\n

The sequence of awards demonstrates that the customized-variant effort has continued across multiple contract actions. However, the publicly available information does not identify the foreign government or fully describe its aircraft requirements.<\/p>\n\n\n\n

Pentagon Has Not Identified the Foreign Customer<\/h2>\n\n\n\n

The identity of the customer remains unconfirmed. Pentagon contract announcements sometimes withhold a foreign buyer’s name when the information is considered sensitive.<\/p>\n\n\n\n

A similar tailored-variant contract surfaced in 2021, prompting aviation analysts to consider which country might be funding the work.<\/p>\n\n\n\n

Key Aero discussed potential customers, including Singapore, which was taking delivery of its first F-35 aircraft around that period.<\/p>\n\n\n\n

That earlier speculation does not establish Singapore as the customer behind the current contract. The Pentagon has not publicly named the country associated with this development effort, and the latest award does not provide enough information to confirm its identity.<\/p>\n\n\n\n

Three F-35 Variants Support Different Mission Requirements<\/h2>\n\n\n\n

The F-35 Lightning II family has three primary variants, each designed for a different operating environment.<\/p>\n\n\n\n
