The biggest issue that afflicts a modern fleet is not affixed by the label of a battle ship: it remains difficult to detect. The rationale of the proposed guided-missile battle ship, BBG(X), as proposed by the Navy fits the more traditional muscle-at-sea paradigm, but its underlying reasoning contradicts the development of maritime warfare, which is towards long-range sensing, distributed pewters, and target networks to punish the high value, high-profile platforms.
BBG(X) is not a classic, even Iowa-type, battle ship and it is not attempting to be. It is described as a ship of between 840 and 880 feet in length and over 35,000 tons of displacement, several times longer than the present day cruisers and destroyers. The front-of-house idea is based on volume: increased vertical launch capacity, increased power generation headroom and increased space to house command-and-control spaces at a time when the Navy is coping with cruiser retirements and the bigger issue of where the air-defense commanders and strike-group staffs are living.
That’s the seductive part. It is the risky portion which is being advertised to an opponent by that size.
Reading it as it is there, the ship does not read like a reborn battle ship, but rather like a missile battle ship on steroids with a layer of aspirational technology tacked on top. Large missile magazines, hypersonic strike and experimental weapons including a 32-megajoule railgun and high-energy lasers in the 300-600 kilowatt range have been linked with the concept. Those add-ons have their own engineering cost: shipboard power, thermal, performance under salt, and shock and continuous operation, and the integration cost of getting all of that to work well with sensors, combat systems, and magazines. The schedule risk is compounded each time a subsystem is made interdependent within one hull that is intended to contain a flagship, even though each subsystem may mature.
The larger strategic problem is survivability in a maritime environment influenced by the constant sensing and long-range weapons. Even large surface combatants are already dealing with the problem of “seen first, targeted first” and increasing the size of the hull does not alter the reality of submarine threat, wide-area maritime ISR and massed missile salvos. It changes the stakes. A ship designed to be able to concentrate firepower, as well as command functions, similarly concentrates its consequences, making them a high-priority target whose loss would be operationally loud even in the event that the rest of the force was taken out.
The reality of industry urges towards the same. BBG(X) suggests a design and construct project on the scale of the most challenging classes of ships built by the Navy, but on a new type of surface combatant. CRS mentions the design work organized in terms of multi-year work and an original concept of a first procurement in the early 2030s, with entry into service, possibly, not until late 2030s or 2040. With a shipbuilding system already dealing with submarines, destroyers, and recovery of capital requirements across the fleet, the opportunity cost is the shadow budget: capacity, skilled labor, and yard bandwidth that cannot be used in other places.
Even the naming controversy refers to the very path. U.S. battle ships were traditionally named after states and carriers usually have the name of the president as anchor, and the “Trump-class” framing could be a magnet of attention, rather than a magnet of acquisition. The greater the extent to which BBG(X) is sold as symbolism the more easily it can be treated as optional as tradeoffs become keen.
BBG(X) eventually seals the standard surface-combatant firepower into a bigger and more conspicuous bag and attaches its justification to technologies and timelines that bring schedule and integration drag. In a time where it is distribution that acts as the check upon precision targeting, the mass as the most characteristic attribute in the concept also turns out to be its most challenging liability to account.
