New Zealand is expanding its naval capabilities with WHAI, an all-electric, jet-powered unmanned surface vessel (USV) designed for near-silent operation and a reduced thermal signature.
The vessel can reach speeds of up to 30 knots (35 miles/56 kilometers per hour) and features a low-profile design intended to support covert operations in contested maritime environments.
Its modular payload bay can accommodate up to 350 kilograms (770 pounds) of equipment, including intelligence, surveillance, and reconnaissance sensors and communications relay systems.
Developed by EDGE Defence, WHAI can operate autonomously or be remotely controlled using existing technologies, and is compatible with third-party command-and-control architectures.
The platform is built with a flexible construction, using materials such as carbon fiber, fiberglass, aluminum, and high-density polyethylene to balance durability and weight.
“WHAI reflects our commitment to delivering cost-effective, future-proofed, deployable capability for defense and security clients,” said John Gell, general manager of EDGE Defence.
“We are seeing a clear shift toward autonomous and uncrewed systems that can extend operational reach while reducing risk to personnel.”
A Multi-Mission USV
WHAI’s mission set includes maritime domain awareness and coastal surveillance in littoral areas, along with force protection and naval training support.
It also supports target simulation and monitoring of critical maritime and subsea infrastructure, such as ports, offshore energy facilities, and communications assets.
Designed for rapid deployment, the USV can be deployed in austere environments where access is limited and conditions are challenging.
“WHAI has been designed from the ground up to meet that need, combining low-signature performance, modularity, and rapid deployability in a New Zealand-developed platform,” Gell added.
“Backed by the support of over 10 local suppliers and subcontractors, WHAI demonstrates how sovereign industry capability can deliver outstanding capability in short time frames.”
