(The red ‘can’ on the side of the CIWS is the LaWS laser…coming to the fleet at least in experimental form as early as this year)
The Navy is intending to add this system to the more than 250 CIWS Phalanx mounts found through the fleet. These devices are the familiar R2D2-looking systems that marry a small radar, fire-control system, and 20mm Vulcan cannon to track targets out to 10 miles away and destroy them once they are within 2.2-miles with accurate gunfire. The addition of the LaWS laser to this will allow the CIWS to engage threats first with the laser then with the 20mm Vulcan if needed.
This combined laser/gun mount, after testing and acceptance will be known as the CIWS Mk 15 Mod 41 with production and fielding in the fleet by 2017.
I found it interesting they are claiming a 2.2 mile accurate range with the CIWS 20mm Blk 15, this would fall into line with the updated barrels, and supports used to make the gun more accurate, as well with a newer effective armor piercing ammo type.
2) The original M61A1 gun barrels were designed for short bursts and were subject to wear and increased dispersion patterns.
The new Optimized Gun Barrels are 18 inches (46 cm) longer, substantially thicker and include a barrel brace and a muzzle restraint to both improve life expectancy and reduce projectile dispersion patterns.
3) The Mark 244 Mod 0 ELC (Enhanced Lethality Cartridges) uses a heavier optimized tungsten alloy penetrator that extends the effective range of this weapon. However, these rounds have been found to increase the likelihood of jams in the ammunition feed system. These jams were the result of the cartridge case getting dented when it was trapped between the feeder unload sprocket and the guide bar just after handoff from the gun bolt. This problem was traced back to the new round having a different center of gravity than previous rounds, which causes the Mark 244 to be mis-positioned in the feed system during the handoff. Alterations of the feed sprocket wheels and guide bars have been recommended to reduce the problem.
The Mk 244 Mod 0 cartridge is known as the ELC (Enhanced Leathality Cartridge). It has a more aerodynamic tungsten alloy penetrator that gives an increase in effective range. Muzzle velocity is 3,650 feet per second (1,113 meters per second) for the Mk 149 cartridge.
The brochure above has contacts with U.S. navy personel and some specifications on the Phalanx LaWS combination capabilities.

Called the CIWS 15 Mod 41
LaWS is an ORDALT to the Mk 15 CIWS that adds a laser weapon
to provide multi-mission, “zero time of flight”, low per shot cost,
and deep magazine capabilities to counter asymmetric threats
(UAVs, jet skis, boats, threat EO/IR sensors, rockets, artillery,
mortars, etc.) beyond existing CIWS hard kill ranges. LaWS will
complement, not replace, the 20 mm gun.
What are its capabilities?
• Counter UAVs
• Counter Rocket Artillery Mortars (CRAM)
• Anti-EO/IR guided anti-ship missiles
• Reversible EO jamming (In band)
• Destructive EO jamming (out of band)
• Counter MANPADs
• Counter Crossing anti-ship missiles (future upgrade with
• Asymmetric Threats (e.g. small boats)
• Laser DazzlerTM/ Hostile Intent determination
• Situation Awareness on both asymmetric and traditional
• EO/IR augmentation to radars
• Floating mine detection
• Counter-ISR (i.e. UAVs, Periscopes)
