The Columbia-class submarine program encountered early setbacks.
The United States Navy’s effort to build its newest class of nuclear-powered ballistic missile submarines is now expected to reach a key milestone in 2028, according to General Dynamics.
The lead vessel, currently under construction, has faced schedule adjustments but is showing signs of steady progress as production challenges are gradually resolved.
First submarine was planned for delivery earlier
Reports revealed that the first submarine in this class was initially planned for delivery earlier, but complications during construction led to a revised target. Issues involving the supply of critical components, along with delays in assembling major sections of the vessel, contributed to the shift in schedule. These obstacles are not uncommon in large-scale defense programs, particularly those involving advanced technologies and highly specialized manufacturing processes.
However, recent updates indicate that the situation is improving. Shipbuilders have reported better coordination with suppliers and increased efficiency within the workforce. As a result, more components are being delivered on time, allowing assembly work to move forward at a more consistent pace, according to reports.
Intended to replace the aging fleet
“District of Columbia (SSBN-826), currently being assembled at GD Electric Boat is on a path to deliver that first boat by the end of 2028, so excellent progress in the last six or nine months on the Columbia program,” GD’s president Danny Deep told USNI during a first-quarter earnings call on Wednesday.
This new class of submarines is intended to replace the aging fleet currently responsible for a significant portion of the country’s nuclear deterrence. Once operational, these vessels will ensure that the United States maintains a continuous and reliable sea-based nuclear capability. Because of this critical role, the program has been given top priority within naval modernization efforts.
Submarine to begin operational patrols around the end of the decade
The Navy plans for the first submarine to begin operational patrols around the end of the decade, aligning with the gradual retirement of older submarines. Maintaining this timeline is considered essential to avoid gaps in strategic coverage.
Work is not limited to just the lead vessel. Additional submarines in the series are already in various stages of construction, with plans to continue building them at a steady rate. The long-term objective is to create a fleet capable of supporting national defense needs well into the future.
Significant funding has been allocated to ensure the continuation of this program, reflecting its importance. The Navy aims to maintain consistent production to avoid further delays and keep overall costs under control.
Despite recent progress, some risks remain. The project still depends on a complex network of suppliers and a highly skilled workforce. Any disruptions in these areas could affect the timeline again. Officials continue to monitor these factors closely while emphasizing the importance of maintaining both quality and safety standards.
Although the Columbia-class submarine program encountered early setbacks, current developments suggest it is moving in a positive direction. The updated 2028 delivery goal represents a realistic adjustment rather than a major derailment. As construction advances and processes become more efficient, the program remains central to the future strength and reliability of the United States’ strategic defense capabilities.
The Fiscal Year 2027 budget request includes $15 billion for the Columbia-class funding line that includes the last tranche of funding for the third Columbia boat Groton (SSBN-828) and full-funding for the fourth unnamed boat, SSBN-829, reported USNI News.

Cool 😎🆒
Hope it’s not made of carbon fiber and a game controller.............
It’s funny the old Poseidon boat I was on displaced a little over 8,000 tons. Things sure have changed. We had a torpedo room too. My 2nd captain drilled the torpedo room guys as hard as us nukes. He remarked after we get rid of these effing missiles we will be Uncle Sam’s biggest fast attack boat.
We were fishing at the mouth of the St. Mary’s river on the Florida side when a Boomer came gliding down the river to the Atlantic. IT WAS HUGE!......................
As complex spacecraft, and likely in a more hostile environment.
Our subs are a marvel.
The air compressor on board my sub compressed the air enough that we could have easily made liquid nitrogen with it. Imagine how quick you could fight fires with a stream of liquid nitrogen directed at it. These new subs should have this possibility built into them .
We did an emergency blow from test depth one time. I wonder what test depth is on these new boats is?
Quite the ride wasn’t it? It turned out to be smoother than I expected. One of the things that impressed me most about traveling around in a submarine was how stable the ride was . Unless you were doing Angles and Dangles or something similar you had no idea you were moving at all.
Yep.
Danny Deep, what a cool name for this company rep.
It will probably be controlled by a bunch of failing electronic modules and soy bean insulated wiring. Maybe it will even run on Windows 11.
When we lost the Thresher off the coast of Maine. Subsafe and Level One quality control protocol was born. Also our boats left the shipyard for shake down cruises without shipyard personnel aboard. That changed. Admiral Rickover considered every boat to be his personal property right down to our training prototypes. He came to ours in Idaho one time. He was a little white haired guy with full bird captains running to get coffee for him. He terrified our Westinghouse Civilian overseers. We never lost another boat out of the yards. Don’t start the USS Scorpion stuff. The boat sailors of that period have our own picture of what that event was. I don’t know what that old boy had on everyone in DC but he got what ever he wanted. We all figured it was Admiral Rickover’s sub fleet and if God went on vacation, he would stand in for him.
We need to at least triple our rate of production of nuclear submarines. Our fleet is aging and the current delivery schedule will not even allow us to replace existing submarines as they reach retirement.
This is one of the biggest national security challenges we have right now.
