Drone boats launching lethal loitering munitions at sea. Containerized missiles strapped to the deck of stealthy ships. The United States Navy is looking at innovative designs like these to better compete with near-peer adversaries like China.
At the end of October, Task Force 59, under orders from the U.S. Naval Forces Central Command (NAVCENT), conducted live-fire exercises around the Arabian Peninsula during Exercise Digital Talon.
Task Force 59, the U.S. Navy’s first unmanned and artificial intelligence task force, used MARTAC T-38 Devil Ray unmanned surface vessels (USVs) to launch several small loitering munitions.
The Devil Ray looks like a typical speed boat. The 38-foot-long craft can carry up to 4,500 pounds and reach burst speeds greater than 60 knots.
For Digital Talon, the Navy equipped Devil Rays with what it’s calling lethal miniature aerial missile systems. Fans of Straight Arrow News may recognize the launch system. It looks an awful lot like the self-contained system AeroVironment uses for its Switchblade 300 drones.
During multiple firing events, the Devil Ray launched aerial drones at a dummy target. The drones hit their mark with 100% accuracy. The Navy said a human operator on the shore made the engagement decisions.
NAVCENT Commander Vice Adm. Brad Cooper said, “During Digital Talon, we took a significant step forward and advanced our capability to the ‘next level’ beyond just maritime domain awareness, which has been a traditional focus with Task Force 59. We have proven these unmanned platforms can enhance fleet lethality. In doing so, we are strengthening regional maritime security and enhancing deterrence against malign activity.”
While the stopping power of the payload carried aboard a Devil Ray may not be enough to take down large ships, USVs armed with essentially GPS-guided rockets will offer naval commanders greater flexibility when planning operations. For instance, Adm. Cooper said they could be used against smaller surface threats like the fast boats used by the Iranian Navy.
For larger threats, when more stopping power is required, supersonic missiles like the SM-6 are a better option. Larger ships like destroyers typically carry SM-6 or similarly sized missiles, which makes them prime targets during a naval engagement. To distribute its firepower, the U.S. Navy is experimenting with putting containerized missile launching systems on various craft.
We already told you about the Navy’s Ghost Fleet launching containerized SM-6 missiles. Now, it looks like the Navy used the same Mark 70 Payload Delivery System from Lockheed Martin on the USS Savannah, an Independence-class littoral combat ship which just so happens to be one of the smallest ships in the Navy.
The 40-foot-long launch system looks like a regular shipping container. Inside, it can hold up to four SM-6 missiles capable of destroying cruise missiles, ballistic missiles, and aircraft out to 150 miles. The Mark 70 PDS is also compatible with weapons used in the Mark 41 vertical launch system, including Tomahawk cruise missiles and Sea Sparrow air-defense missiles.
Putting a Mark 70 PDS on a littoral combat ship does sacrifice stealth, but it instantly increases the vessel’s firepower far beyond anything it currently carries. Containerized launch systems could also offer new life to a class of vessels that has largely under-delivered on expectations.
