(Navy) The U.S. Navy’s $122.3 billion Columbia-class ballistic missile submarine program is off to an inauspicious start after faulty welding was discovered in several missile tubes destined for both the Columbia and Virginia-class programs, as well as the United Kingdom’s follow-on SSBN program.
In all, 12 missile tubes manufactured by BWXT, Inc., are being scrutinized for substandard welds. Seven of the 12 had been delivered to prime contractor General Dynamics Electric Boat and were in various stages of outfitting, and five were still under construction. The Navy and Electric Boat have launched an investigation, according to a statement from Naval Sea Systems Command spokesman Bill Couch.
The bad welds came to light after discrepancies were discovered with the equipment BWXT used to test the welds before shipping them to GDEB, according to a source familiar with the issue.
The discovery of a significant quality control issue at the very outset of fabrication of Columbia injects uncertainty in a program that already has little room for delays. The issue is made even more troubling because it arises from a vendor with an excellent reputation, and raises questions about whether the Navy can deliver Columbia on time, something the Navy says is vital to ensuring continuous nuclear deterrent patrols as the Ohio class reaches the end of its service life.
The issue with the missile tubes, part of the common missile compartment to be installed in both Columbia and the UK’s Dreadnought submarine program, should not put the Columbia program behind schedule, Couch said. The impact on Royal Navy’s Dreadnought program is less clear, Couch said.
“Impacts to the delivery of missile tubes to the UK will be assessed upon completion of GDEB’s efforts to define and scope next steps,” Couch said.
BWXT is one of three vendors sub-contracted to deliver tubes for Columbia and Dreadnought and one of two on contract for Virginia class, Couch said. The quality control issue not only impacts the U.S. and U.K. ballistic missile submarine programs, but might also impact the schedule for the Navy’s next iteration of the Virginia class , Virginia Block V, which incorporates additional vertical-launch missile cells, known as the Virginia Payload Module.
“The Navy/GDEB team is working to bound the scope of the problem and engineering assessments are ongoing to assess and determine remediation for the identified issues,” Couch said. “Initial reports indicate that the other vendors do not have the same issue, and they continue to produce missile and payload tubes.”
The Navy awarded General Dynamics a $101 million contract for SSBN missile tubes back in 2016 . Design work for the common missile compartment goes back nearly a decade. In September, the Navy awarded a $5.1 billion contract to General Dynamics Electric Boat to finish design work for the boat ahead of beginning construction in 2021.
