RTX Corp. has won a $206.2 million contract to upgrade the system that guides fighter jets onto aircraft carrier flight decks when pilots cannot see the ship, a deal that shifts one of the Navy’s most critical aviation programs from production into a new phase of modernization against electronic warfare threats.
The contract, awarded in spring 2026 and posted to the federal procurement portal sam.gov, tasks RTX’s Collins Aerospace division in Cedar Rapids, Iowa, with delivering software and hardware improvements to the Joint Precision Approach and Landing System, known as JPALS. Work is expected to run through December 2028.
The award comes after the Navy accepted the final JPALS production unit, closing out the manufacturing line and opening a chapter focused on keeping the technology viable as adversaries field increasingly sophisticated GPS-jamming and spoofing capabilities.
Why JPALS matters on the flight deck
Landing a jet on a carrier is already one of the most demanding tasks in military aviation. The flight deck is roughly 1,000 feet long and pitching in open ocean swells. At night or in heavy weather, pilots depend almost entirely on instrument guidance to find the ship and catch an arresting wire.
JPALS replaced older radar-based landing aids by broadcasting a local, GPS-augmented signal from the carrier to approaching aircraft. That signal provides precision course and glideslope data accurate enough to bring an F-35C Lightning II or an F/A-18E/F Super Hornet down the chute in conditions where legacy systems like the AN/SPN-46 precision approach radar would struggle or fail entirely.
The system has been a required element of F-35C carrier operations since the jet reached initial operational capability, and it is installed on the Navy’s Gerald R. Ford-class carriers and has been progressively fielded across Nimitz-class ships. Without it, the newest and most expensive aircraft in the carrier air wing cannot safely recover to the ship in degraded conditions.
What the contract covers
According to the detailed contract notice, the deal is structured as a fixed-price incentive agreement. That vehicle sets a target cost and profit but allows adjustments based on actual performance, with RTX absorbing overruns up to a negotiated ceiling. The structure signals that the Navy considers the underlying technology mature enough to define firm requirements rather than funding open-ended research.
Collins Aerospace will deliver upgrades designed to strengthen JPALS performance during active signal jamming, degraded GPS environments, and severe weather. The specific technical changes, such as new anti-jamming algorithms, upgraded antennas, or tighter integration with inertial navigation backups, are not disclosed in the public contract abstract. Defense programs routinely classify performance specifications at this level of detail.
The bulk of engineering and integration work will take place at Collins Aerospace’s Cedar Rapids facility, which has served as the primary JPALS development and manufacturing site since the program’s inception more than a decade ago. Related procurement actions documented in earlier JPALS postings on sam.gov trace the system’s progression from development through low-rate initial production and into full-rate manufacturing.
The electronic warfare backdrop
The Pentagon has grown increasingly vocal about the threat that GPS denial poses to military operations. The Department of Defense’s own assessments have flagged GPS-dependent systems as vulnerable in contested environments, particularly in scenarios involving near-peer adversaries equipped with advanced electronic warfare suites.
For carrier aviation, the stakes are acute. A jammed or spoofed GPS signal during a night recovery in the Western Pacific is not an abstract risk; it is the kind of scenario the Navy trains for and worries about. The decision to invest more than $200 million in JPALS modernization, rather than simply sustaining the existing hardware, suggests the service believes the current system needs meaningful technical improvements to remain reliable under those conditions.
The upgrade can be read as part of a broader Navy effort to harden carrier operations against electromagnetic threats, alongside investments in shipboard electronic warfare systems, communications resilience, and navigation alternatives that reduce dependence on any single signal source.
Open questions for the program
Several significant details remain unclear from public records. RTX has not issued a public statement about the award, leaving questions about subcontractor involvement, schedule risk, and the exact cost-sharing ratio under the incentive structure unanswered.
The relationship between the JPALS upgrade and the F-35’s own avionics modernization timeline is also unresolved. The F-35 Joint Program Office manages its own block upgrade schedule, and any changes to the landing system’s aircraft-side software must align with those baselines. Whether the Collins Aerospace work will feed into the F-35’s planned Block 4 upgrade or proceed on a separate track has not been specified. Misaligned timelines between ship-side and aircraft-side systems could delay operational fielding even if the hardware is ready on schedule.
How the Navy will sequence installation across the carrier fleet is another gap. The contract period running through late 2028 suggests a phased rollout, but public records do not indicate whether front-line carriers headed for high-tempo deployments will receive priority, or how much maintenance availability each ship will need to complete the integration.
What the deal means for RTX
For defense industry watchers and investors tracking RTX’s government services revenue, the $206.2 million award adds to a growing backlog of sustainment and modernization work. These contracts tend to generate steadier margins than new-start development programs, which carry higher technical and financial risk.
Collins Aerospace’s position as the sole JPALS provider is central to the business case. The contract was awarded without competition, a common arrangement for complex military systems where switching vendors would require costly redesigns and extensive new testing. From a revenue perspective, the deal reinforces RTX’s long-term role in carrier aviation infrastructure at a time when frontline attention often focuses on higher-profile aircraft and weapons programs.
The broader signal is straightforward: carrier aviation will continue to depend on JPALS for precision recoveries, and the Navy is willing to invest heavily to ensure that dependence holds up against the threats it expects to face through the end of the decade and beyond.
