Today’s top story is a twin-blockbuster for Huntington Ingalls Industries (HII): the Navy has awarded $76.6 billion in contracts for the construction of Block VI Virginia-class and Build II Columbia-class submarines. This isn’t just an acceleration of existing trends, it’s a veritable undersea arms race that will shape global naval power dynamics for years to come.

U.S.-China Undersea Arms Race Heats Up

While today’s news was all about American contracts, let’s not forget the elephant in the room: China. Last week, The War Zone reported that China has fielded its YJ-20 hypersonic anti-ship missile aboard smaller destroyers. This isn’t a one-off; it’s part of Beijing’s broader strategy to distribute advanced weaponry across its surface fleet.

The U.S., meanwhile, is playing catch-up with these massive submarine contracts. The Virginia-class deal alone will keep Newport News Shipbuilding (NNS) busy until 2034, while the Columbia-class program will sustain production through at least 2031. Lockheed Martin also bagged a whopping $58.62 billion contract to beef up U.S. air defense capabilities with PAC-3 MSE interceptors.

Next-Gen Shipbuilding: Jobs and Innovation

What do these contracts reveal? For one, they’re a significant vote of confidence in next-gen shipbuilding technologies. NNS will serve as the delivery yard for six Virginia-class submarines and is a major partner in the Columbia-class program, producing module sections for each submarine.

The money trail also hints at job growth: Lockheed Martin’s PAC-3 MSE contract alone promises around 1,850 jobs in Camden, Arkansas by 2030. Expect more employment ripple effects as contractors scale up production and expand supply chains.

AUKUS and Beyond: Allies Join the Submarine Arms Race

It’s not just the U.S. upping its submarine game. Australia selected Leidos Gibbs & Cox for AUKUS dry dock design, supporting its nascent conventionally-armed, nuclear-powered submarine fleet. This is another step forward in the trilateral security partnership that has already seen French frustration over a canceled diesel-electric submarine deal.

But it’s not all about subs today. Here are a few other developments worth noting:

Pentagon’s Robot Boat Contest: DIU is offering $100 million for robot boats capable of launching attack drones, signaling a shift towards autonomous warfare. First Live-Fire Exercise for US Navy’s GARC: The Global Autonomous Reconnaissance Craft (GARC) demonstrated its mettle off Hawaii during Rim of the Pacific exercises.

What Else Moved

Hanwha Ocean signed partnerships with Leidos to advance naval vessel development and workforce cooperation. Meanwhile, Australia’s selection of Leidos Gibbs & Cox for AUKUS dry dock design underscores the growing importance of allies in global defense cooperation.

Forward Look

As the U.S.-China submarine arms race shows no signs of abating, watch for more contracts, partnerships, and technological advancements in undersea warfare. Also, keep an eye on AI, autonomy, and cyber capabilities – they’re all top trends from the last 30 days that continue to shape defense priorities.
