Mk 70 will give the LCS fleet “tremendous firepower and even more tactical advantage over our adversaries,” Del Toro said during the

Del Toro’s comments this week suggest the sea service is bullish on what the Mk 70 can do to reverse the LCS’s fortunes and finally get the ships ready for a higher-end fight, even as questions remain about the LCS’s survivability if they are indeed dispatched “aggressively,” as Del Toro noted.

“LCS is back, Freedom class and Independence class, and we have every intent to deploy them aggressively everywhere around the globe, and the Persian Gulf, obviously, with the mine-sweeping capability and everywhere else it’s needed, particularly in the Pacific with these added capabilities,” Del Toro said.

was the first to report Del Toro’s remarks.

TWZ has reached out to the Navy to get more information on the timeline for the upgrades, and which LCSs will be involved.

The Mk 70 is already being rolled out on some LCS, with images from the USS Nantucket’s (LCS-27) commissioning in November 2024 revealing that launcher in place.

Such a capability would allow LCS to fire smaller volumes of several types of missiles, and would be particularly important in a

previously laid out what the Mk 70 would offer after the Navy announced Savannah’s successful test-fire:

“The Mk 70 family does offer a relatively simple way to increase the firepower on a wide variety of ships with suitable deck space. This includes smaller surface combatants with helipads like Independence class LCSs,

, and certain

commercial designs. The containerized launcher provides immense flexibility just with its ability to fire SM-6s and Tomahawks, and its Mk 41 VLS heritage means more munition options could definitely be integrated in the future.”

The multi-purpose SM-6 can be used against a variety of air and

that is expected to offer greater range and hypersonic peak speed.

Loading a Mk 70 launcher with

would drastically increase the LCS’s capabilities, allowing the class to strike land and sea targets within an area extending roughly 1,000 miles in all directions, which would help hold targets in areas with substantial ******** defenses. The Tomahawks can also loiter over a target and have their target changed mid-flight.

The Savannah test-fire wasn’t the first time we’ve glimpsed such a setup aboard a LCS.

Del Toro did not mention what sort of sensors would accompany Mk 70 launchers on a LCS. But for SM-6 and Tomahawk, remote sensor and targeting data from external platforms — including those in the air, at sea, on land, and in space — that is datalinked to the ship would likely be the most feasible option considering the LCS’s limited sensor suite. This concept of distributing missiles across more vessels and locales and decentralizing their fire control and targeting has long been of major interest to the Navy.

But strapping on other sensors is a possibility too. For instance, ship spotters picked up what appeared to be a trailer-mounted

what else such a radar, also known as the

, would contribute, including the improved ability of Mk 70-equipped ships to spot and engage targets independently, regardless of a ship’s built-in capabilities. It offers an example of how systems could be lashed to the ship’s deck to help expand its sensor capabilities for tailored mission sets.

Del Toro also noted Wednesday that “numerous” LCS are now equipped with the

But while the Mk 70 launcher and NSM give the LCS fleet some added firepower, there are tradeoffs, as TWZ has reported:

“With regard to the Navy’s LCSs, it is worth noting that using the rear flight deck as a place to mount a Mk 70-series launcher and other associated equipment eliminates their ability to launch and recover helicopters. The service has long touted the ability of the ships to

, as key to helping the ships find and engage targets at extended ranges, defend against close-in threats like small boat swarms, and just provide increased situational awareness.”

Such a tradeoff would be a massive one for the LCS as its flight deck and embarked aviation capabilities are highly prized and greatly expand the ship’s flexibility and independence of operations. Giving up that capability for just four missiles per Mk70, presumably at least three systems can be carried, is a big concession. It is possible that

• Sign Up

could be quad-packed into each cell like they are on Navy Mark 41 systems.

This would offer the LCS 16 missiles per launcher, but those would be used for self defense and up to medium-range area air defense, that is if the LCS’s sensors can support their employment. The data-link equipped
