The Defense Innovation Unit (DIU), which Kongsberg's release calls the "Department of War Innovation Unit," is buying more autonomous underwater vehicles from Norway's Kongsberg, widening a prototype effort that already linked the company with DIU and the US Navy. Kongsberg Gruppen ASA said it received what it called a "major contract modification" for autonomous underwater capabilities, according to the company's Oct. 29 announcement. The modification to a Prototype Other Transaction Agreement is valued at USD 54 million.
Kongsberg's release, republished by Naval News on Oct. 30, says the modification "is primarily driven by the delivery of a broad range of autonomous underwater vehicles (AUVs), alongside associated underwater capability components." Neither the company nor Naval News disclosed the value of the original agreement, how many vehicles the modification covers, which models are included, or when deliveries will take place.
What the $54M Modification Buys
The announcement describes the purchase in broad terms: a range of AUVs plus the components that make up a working underwater capability. Kongsberg did not name specific vehicles in its text. Naval News illustrated its report with a Kongsberg photo of the HUGIN Endurance UUV, though the article does not say that model is part of this order.
Kongsberg described itself as having "more than 30 years of proven experience in autonomous underwater vehicles" and said it "continues to develop and deliver trusted large AUV systems for defence and commercial customers worldwide." That dual market matters to the structure of the deal. When the same core vehicle designs can serve commercial and naval customers, a defense buyer can adapt a mature platform rather than fund a clean-sheet design.
Chief Executive Eirik Lie framed the award as a continuation rather than a new start. "This contract continues our collaboration with DIU and the US Navy and reflects confidence in KONGSBERG's autonomous underwater technology," Lie said. He added that the deal "demonstrates the value of our dual-use portfolio in delivering defence capabilities and further strengthens our position as a technology and defence company."
Why DIU Used a Prototype OTA for Underwater Drones
A Prototype Other Transaction Agreement sits outside the Federal Acquisition Regulation. DIU uses the vehicle to test commercial technology with military users quickly, and successful prototypes can move into follow-on production without a new full competition when the original solicitation allowed for it. Modifying an existing agreement, as DIU did here, adds money and scope to a relationship that is already running instead of starting a fresh solicitation.
That approach fits a program where the government wants hardware in the water for experimentation. Because the announcement does not identify the original solicitation, the base award date or the agreement's ceiling, outside observers cannot yet tell whether this modification marks an expansion of prototyping or a step toward production quantities. Kongsberg's wording points to delivery of vehicles and components as the main driver, which suggests hardware rather than study work.
How the NOK 1.7 Billion AUV Year Shapes Kongsberg's Undersea Push
The DIU award lands in a strong year for Kongsberg's underwater business. Camilla Kiss, Executive Vice President and President of the company's Discovery division, put a number on it: "So far in 2026, we have signed AUV contracts worth a total of NOK 1.7 billion across all markets."
Kiss tied that figure to a deliberate strategy. "This progress supports our strategic ambition to grow in undersea warfare and strengthens the foundation for continued development," she said. The company released the announcement on the same day it published its third-quarter 2026 results, which it headlined as a record-high order backlog.
Kiss also pointed to the technology driving demand. "Advances in artificial intelligence, edge processing and autonomy are enabling platforms to undertake increasingly complex missions with greater persistence and operational effectiveness. We are at the forefront of this development," she said. Persistence is the central selling point for large AUVs: vehicles that stay submerged longer and make more decisions on their own need less support from a crewed ship nearby.
For US contractors, the award shows a separate acquisition path at work: a foreign-headquartered maker of undersea vehicles supplying the Pentagon through DIU's commercial-technology channel rather than a traditional program office.
What It Means for Contractors
The award offers several signals for companies working in the undersea market or eyeing DIU as a customer.
DIU keeps funding undersea autonomy through existing agreements. A $54 million modification to a prototype OTA shows DIU is willing to add substantial value to an agreement already in place rather than start a new solicitation. Firms that win an initial prototype slot gain a position that can grow without a new solicitation. Firms outside that slot have fewer openings to break in once an agreement is running.
Commercial heritage remains a competitive asset. Lie's emphasis on the "dual-use portfolio" suggests that vehicles already proven in commercial work carry weight with defense buyers. Vendors with vehicles proven in commercial survey or energy work can point to operating hours and production history, which can shorten the path to a prototype award.
Subcontract and component openings may follow. The announcement says the modification covers "associated underwater capability components" alongside the vehicles. Companies that supply payloads, sensors, navigation, communications, launch and recovery gear, batteries or mission software should watch for teaming and supply opportunities, especially if any work shifts to US facilities. Kongsberg has not announced US production or partner arrangements tied to this award.
Foreign-owned primes are competing directly for autonomy work. Kongsberg is a Norwegian company, and the announcement describes a DIU agreement rather than a foreign military sale. US firms in the undersea market should expect allied competitors on OTA solicitations and should factor that into teaming decisions, where pairing with an established foreign platform maker can be as viable as competing against one.
Key details remain undisclosed. The base agreement value, vehicle count, delivery schedule and the US Navy units involved were not released. Contractors tracking this effort should watch for DIU solicitations, Navy budget documents and any further company disclosures before drawing conclusions about the size of the eventual market.
