Railguns, Lasers and Long Range Missiles to be Part of US Navy's Future Surface Ships

“I’ve never wanted to enter any tactical scenario where all I had is a defensive capability. It’s a losing proposition,” said the chief of Pacific Command, Adm. Samuel Locklear. “You will defend yourself until you’re dead.”

That was the PACOM commander’s blunt and public response when I asked him about the chronic imbalance between the offensive and defensive capabilities of the Navy’s surface warships: its cruisers, destroyers, frigates, and controversial new Littoral Combat Ships. Other admirals had angsted over the issue at last week’s annual conference of the Surface Navy Association here, but it’s no coincidence the man who’d have to command any war with China was the bluntest.

The Navy’s has a three-step plan to boost firepower:
  1. In the short term, revive the long-range skip-killing capability it lost when it phased out the 600 -mile-range Tomahawk Anti-Ship Missile (TASM) years ago.
  2. In the mid term, free up missile launchers for offensive use by replacing defensive missiles — each of which can be used against incoming enemy aircraft or missiles just once — with lasers that can keep firing as long as the ship’s generators turn.
  3. In the long term, equip ships with electromagnetic rail guns that can launch solid metal slugs at targets over the horizon at seven times the speed of sound.

“With respect to lasers, we’re talking more about defense,” said Rear Adm. Thomas Rowden, director of surface warfare for the Chief of Naval Operations (staff section N96), when I pulled him aside at the conference. “On the offensive side of the house, we have the electromagnetic rail gun.” Both will be able to fire far more times than any set of missile launchers; the laser will, in theory, hit incoming missiles at literally the speed of light; and the rail gun can fire projectiles at the enemy at velocities no missile can match.

“If you’re getting Mach 7,” Rowden told me, “speed is a difficult thing to defend against.”

That said, rail guns will complement long-range missiles, not replace them: While the rail gun shot would be harder to dodge, the missile can go much farther.

“We’ll have to see what kind of range we’re going to get out of the railgun,” Rowden said. So, I asked, would it ever be comparable to a Tomahawk cruise missile? The admiral laughed out loud. “No! I think it’d be Mach 40 or something like that to get the kind of range.” Rail gun tests to date have suggested they could hit targets up to 125 miles away.

All these weapons, of course, are in the near future.


I would expect the next naval warship - whether its a destroyer or cruiser - to incorporate the above.   The Ticos will need to be replaced soon.  Four FELs, a pair of railguns and 128 to 192 VLS cells would be a rather scary beast.
