A Highly Modular and Flexible Design
One of the most significant features of the Ghost Shark is its highly modular and flexible design. This design philosophy allows the UUV to be easily reconfigured to accommodate different payloads, making it suitable for a wide range of missions. The Ghost Shark’s modular hull sections are designed with integrated data and power buses, enabling rapid integration of various payloads, from ISR sensors to strike capabilities. This modularity is further enhanced by the vehicle’s lack of large, extendable masts, which are common in other UUV designs. Instead, the Ghost Shark features a lower-profile swept-back sail on its nose section, allowing for greater flexibility in payload orientation.
According to Dr. Shane Arnott, Senior Vice President for Engineering at Anduril and the company’s maritime lead, the modular nature of the Ghost Shark allows for significant scalability in its design. The vehicle’s payload sections are much larger than many other UUVs, providing ample space for a wide variety of payloads. Arnott emphasized that the Ghost Shark’s design is highly extensible, meaning that additional sections can be added to the vehicle to accommodate even larger payloads. This flexibility is particularly important in undersea warfare, where the ability to adapt to different mission requirements is crucial.
Military and Commercial Applications
While the Ghost Shark was initially developed for military purposes, Anduril has also received significant interest from commercial sectors. The vehicle’s ability to perform seabed surveys and interact with objects on the seafloor makes it an attractive alternative to tethered remotely operated vehicles (ROVs) and larger surface vessels. This dual-use capability is indicative of a broader trend in the defense industry, where technologies developed for military applications are increasingly being adapted for commercial use.
On the military side, Anduril has received requests for over a dozen new payloads for the Ghost Shark, indicating a high level of interest in the vehicle’s capabilities. While specific details about these payloads remain scarce, it is likely that they will include advanced sonar systems, electronic warfare capabilities, and possibly even kinetic strike options. The Ghost Shark’s ability to serve as a “mothership” for smaller uncrewed systems is another key feature, allowing it to launch and control autonomous swarms of UUVs. This capability is particularly important in contested environments, where the ability to deploy and control multiple autonomous systems can provide a significant tactical advantage.
