“To be blunt, it’s hard for 4,600 sailors to spend weeks and months on a ship without fully functioning toilets,” Steve Walsh of WHRO said in an NPR interview.
That is the engineering paradox that happens after the USS Gerald R. Ford: a next-generation aircraft carrier that was designed to produce combat power at scale and have its crew at war fighting against a system that was as primitive as the onboard sanitation. Having a crew in the thousands and deployment well beyond normal peacetime routines, small technical failures cease to be small. They are a source of schedule issues, maintenance, and morale issues that add up throughout a floating city.
The pace of deployment of the ship has been made a case study of what happens when platform ambition and calendar reality collide. The deployments of carriers are usually organized into a six-month cycle, but the outout of the Ford has long since unearthed this pattern and, as the main article reports, as far as 11 months. Sailors and families explain the foreseeable impacts of the unforeseeable, due to missing funerals, stunted plans, and exhaustion as a result of working on complicated equipment with minimal rest. A letter by commanding-officer that was received by the Wall Street Journal admitted that sailors were “coming to accept” the fact that they could miss weddings and family trips, but they were still required to go when needed.
The sewerage issue provides a physical advantage to that strain. Ford relies on a vacuum sewage system borrowed partially by the cruise ship industry to save water however, the working conditions are more severe and the pattern of use is not as lenient as a commercial vessel. The system is separated into areas and there is a cascading effect to failures: one failure can cause suction in one area to fail, knocking out several heads simultaneously and leaving sailors to walk, wait and operate around a closure. When a significant percentage of the ship toilets fail, the shock is felt in every shift of the watch, on each maintenance crew, on each compartment with a queue of people established outside the compartment.
The processing of a 205 maintenance calls in less than four days in a single spike was reported in documentation as cited in the NPR transcript, and sailors worked 19-hour shifts to hunt down leaks and fix the situation. The described clogs and failures were not extraordinary, as it is calcium deposits, loose components, and objects that should not be in the plumbing system getting into the pipes. In the case of a vessel (with approximately 650 toilets) even a “single maintenance call per day” is an operational background noise that is slowly eating manpower.
There is mitigation, but it is neither fast nor graceful. A report by Government Accountability Office cited by NPR cited a transitory solution of acid flushing to clean the system, which was effective, but challenging to implement in deployment cycles. That puts us in the trap of maintenance: extended deployments not only squeeze the time to do thorough maintenance but also add strain, usage, and the effects of partial outages.
The plumbing problems at Ford end up in an expanded narrative of modernization. The vessel was constructed on the basis of new systems that were to enhance generation of sorties, decrease manpower as well as to increase the flexibility in future air wings. The redesign of the historically hydraulic arresting gear that has been digitally controlled, the Ford-class Advanced Arresting Gear (AAG), is one example. The idea behind AAG is simple engineering: it can modify the energy absorption in real time depending on the weights and velocities of the aircraft and this way enables the aircraft to be less stressed with the airframes and allows a broader mix of platforms with the include of lighter unmanned systems. However, as in most first of kind integrations, the initial reliability and software challenges have become the focus of criticism and have required repeated corrections.
Collectively these threads present the carrier as something beyond the reach symbol. It is a controlled ecosystem in which high-tech launch-and-recovery, utility of industrial scale and human survivability are closely integrated. The bottleneck on a vessel that is likely to produce a lot of production can change rapidly, say, between catapults and arresting engines or between valves, vacuum piping, and the overheated technicians who keep it all running.
