The Naval Air Systems Command awarded General Atomics a $15,575,652 contract modification (N0001914C0037 mod P00116) on May 21, 2026, to resolve Electromagnetic Aircraft Launch System deficiencies aboard USS Enterprise (CVN-80), focusing on transformer rectifier failures in the Prime Power Interface Subsystem and a full migration of the EMALS network from copper cabling to single-mode fiber infrastructure, with work required to be complete by April 2028.
EMALS Reliability History on Ford-Class Carriers
The Electromagnetic Aircraft Launch System replaced steam catapults on Ford-class carriers with a linear induction motor system driven by stored electrical energy. The system debuted operationally on USS Gerald R. Ford (CVN-78), where transformer rectifier units in the Prime Power Interface Subsystem proved to be a persistent maintenance burden during the ship's early operational years. The PPIS is responsible for converting ship's electrical power into the precise high-voltage pulses that drive the linear induction motor — any instability in that conversion chain directly degrades launch performance or halts flight operations while the system is reset and tested.
USS John F. Kennedy (CVN-79), the second Ford-class carrier, incorporated modifications informed by Ford's experience, but transformer rectifier design limitations were not fully resolved before Enterprise's construction had already progressed past the point where the existing design was built in. The May 2026 modification addresses that gap directly, funding targeted engineering changes rather than accepting the same maintenance cycle that burdened Ford's early operational schedule.
The contract modification also targets digital synchronization weaknesses identified during analysis of the EMALS network architecture on earlier hulls. Synchronization errors between launch control nodes can cause launch aborts or degraded catapult performance. Each launch abort during high-tempo flight operations has downstream consequences for strike planning and sortie generation rates — the metric carrier strike group commanders use to measure a carrier's combat effectiveness. Addressing these issues on Enterprise before the ship enters sea trials reduces the likelihood of those operational penalties appearing after delivery.
The PPIS integrates with energy storage systems that charge between launches and discharge in controlled pulses during the catapult stroke. Transformer rectifier failures in that chain don't just stop individual launches — they can put entire launch sections offline until the fault is diagnosed and the failed unit replaced. On a Ford-class carrier with four catapult lanes, losing a launch section cuts sortie generation capacity significantly. The modifications funded under this award redesign or replace the rectifier components most prone to failure under sustained operational load.
Copper to Fiber: The Network Migration
The EMALS control network on earlier Ford-class hulls uses copper data cabling to pass timing and command signals between launch controllers, energy storage modules, and the Prime Power Interface Subsystem. Copper works adequately under normal conditions, but it introduces latency variability and is susceptible to electromagnetic interference — a meaningful concern aboard a ship that generates enormous electromagnetic fields during each aircraft launch cycle. Over time, those interference events can corrupt timing signals and contribute to the synchronization weaknesses that this contract modification is specifically designed to correct.
Single-mode fiber carries signals as pulses of light rather than electrical current, which makes it inherently immune to electromagnetic interference and reduces signal latency to near-theoretical minimums. For a system like EMALS where microsecond-level timing precision governs whether a catapult delivers consistent energy profiles to different aircraft types — from lightweight training aircraft to heavy strike fighters — that immunity is operationally significant. Single-mode fiber also supports substantially higher data throughput than the copper it replaces, which gives future software upgrades more bandwidth headroom without requiring another physical infrastructure change.
The migration is architecturally more complex than a simple cable swap. Fiber requires optical transceivers at every network node, different termination hardware, updated cable routing through the ship's infrastructure, and a qualification process to verify that the new network meets EMALS timing specifications under shipboard operating conditions including vibration, temperature cycling, and the electromagnetic environment generated by the launch system itself. Completing this on CVN-80 while still under construction at Newport News Shipbuilding is substantially easier than retrofitting the same infrastructure on a commissioned carrier during a maintenance availability, which is why NAVAIR elected to fund this now rather than defer it to a post-delivery period.
What It Means for Contractors
General Atomics holds the prime EMALS contract and serves as the system integrator for the launch system across the Ford class. The actual fiber installation aboard CVN-80 will flow through the carrier construction contract at Newport News Shipbuilding, which means subcontract opportunities for the physical installation and integration work sit primarily within Newport News's existing supply chain. Contractors with established subcontract relationships at the yard — particularly those qualified for electrical and electronic systems installation — should monitor whether this modification generates follow-on task orders for fiber termination work, optical network testing, or PPIS component integration.
The EMALS subcontract ecosystem that feeds into the General Atomics prime includes suppliers for energy storage capacitors, linear motor components, power electronics, and previously, shipboard copper cabling. The shift to single-mode fiber creates new demand for optical transceiver procurement, fiber cable procurement to Navy shipboard qualification standards, and the specialized labor needed to terminate and test single-mode fiber runs in a shipboard environment. Contractors already performing qualified fiber installation work at Newport News are best positioned to capture that work without going through a new qualification process.
The April 2028 completion date aligns with Enterprise's anticipated construction milestone schedule ahead of delivery. Contractors bidding on related task orders should account for the inherent schedule risk in any major shipbuilding program — delays in CVN-80's broader construction timeline could shift the integration window for EMALS network work accordingly. Tracking NAVSEA and NAVAIR solicitation portals for task orders under the N0001914C0037 contract vehicle is the most direct way to identify downstream opportunities as this modification moves into execution and scope is broken into discrete engineering and installation packages.
Beyond the direct scope of this modification, the EMALS network upgrade on Enterprise sets a technical baseline for how the Navy will approach similar infrastructure work on future Ford-class hulls. CVN-81 and CVN-82 are under various stages of planning and early construction, and the lessons from migrating Enterprise's network to single-mode fiber — qualification procedures, installation methods, testing protocols — will inform how those ships are designed from the outset. Contractors who develop expertise and documentation through Enterprise's upgrade position themselves as knowledgeable sources for that follow-on work as the Ford class continues to grow.
