The protagonist is the new generation of nuclear submarines of the Columbia class, whose first example, the USS District of Columbiais moving towards its planned delivery in 2028. With 21,000 tons of submerged displacementit will be the largest submarine ever built by the United States. and the quietest
To understand the scale, just imagine a steel cylinder more than 170 meters long, capable of remaining hidden under the ocean for months, without needing to refuel throughout its useful life. His nuclear reactor is designed to last the entire life of the submarineeliminating the recharging stops that previous generations did need. But size is not the most important thing.
What defines these submarines is their function. They are ballistic submarines, that is, they are part of the so-called “nuclear triangle”: land, air and sea. Their mission is not to strike first, but to ensure that even in the worst-case scenario imaginable, the United States can respond. Each unit will be equipped with 16 Trident II missilescapable of traveling more than 11,000 kilometers at speeds approaching 30,000 km/h and carry multiple nuclear warheads.
The program, however, is not without pressure. The urgency to have the first submarine ready is such that, in the words of Vice Admiral Rob Gaucher, responsible for the program, its delivery is nothing short of critical. “On-time delivery is a matter of life and death”, recently stated Gaucher. The phrase may sound exaggerated, but it reflects a reality: these submarines must progressively replace the current Ohio-class fleet, which begins to retire starting this decade.
The technical challenge is not minor either. Build one of these submarines characteristics involves coordinating thousands of suppliers, advanced silent propulsion technologies and ultra-high precision weapon systems.
In fact, the program itself has suffered delays in recent years, although it now appears to be stabilizing. According to those responsible for the project, the first submarine is already around 65% complete. and is moving towards delivery in 2028.
“It will be an enormous effort,” they acknowledge from the Pentagon, underlining the industrial complexity of the project. There is one especially revealing detail: the US Navy has defined this program as its top acquisition priority. That means that, In budgetary and strategic terms, it is above many other defense systems.
