A couple of 30mm autocannon and Hellfire missiles are no more than adding a missing "self defence package"
The modular design of the platform allows weapons and sensors of all types:
Norwegian company Kongsberg Defense & Aerospace proposed equipping LCSs with their radar-evading Naval Strike Missile, presenting scale models of the Freedom-class with 12 NSMs and the Independence-class with 18 NSMs.[46] In July 2014, the Navy confirmed that it would test-launch the NSM from the USS Coronado (LCS-4) to evaluate feasibility, the first time an LCS will fire a surface-to-surface missile. The NSM has a range of 100 mi (87 nmi; 160 km), greater than the Harpoon anti-ship missile; but LCSs lack long-range fire control systems to detect targets at this distance.[47] On 24 September 2014, the NSM was successfully fired at a mobile target. The LCS' modular design makes it possible to add weapons and sensors as part of the warfare suite. This could mitigate lethality criticism of the LCS, which is oriented toward asymmetric swarm boat threats than comparable surface combatants.[48]"
