HIMARS For The Navy

ComNavOps, along with many readers, has called for looking into the possibility of mounting a Multiple Launch Rocket System (MLRS) on ships to provide firepower support for troops ashore. 

To refresh your memory, the Army’s M270 MLRS  can fire, among other munitions, 12 guided rockets with a range of 60+ km (37+ miles) with a unitary high explosive (HE) warhead or a payload of 404 M85 submunitions.  Alternatively, the MLRS can fire the MGM-140 Army Tactical Missile System (ATACMS) which is a ballistic missile with a range of 300 km (186 miles) and a 500 lb HE warhead.  ATACMS is being upgraded with a new seeker to enable it to hit moving targets including targets at sea.  The missile occupies the same space as six of the smaller rockets in the MLRS launcher enabling two to be fired from a single launcher.

The Army seems to be replacing the MLRS with the M-142 High Mobility Artillery Rocket System (HIMARS) which is a lighter version of the MLRS but with only half the weapon capacity.  Thus, a HIMARS can fire 6 smaller rockets or 1 ATACMS.

We see, then, that the Army already has the long range rocket system that the Navy has spent $24 billion dollars on in the form of the Zumwalt program and which has totally failed due to the prohibitive cost of the rockets.

To bring us completely up to date, USNI News website reports that the Marines have test fired a HIMARS system from the deck of an amphibious ship (1).  This is both good news and stupid news.


HIMARS - Publicity Stunt With Potential


First, the stupid …  Firing HIMARS from the deck of a ship is a publicity stunt, at best.  Such an application is unworkable for a variety of reasons.  The HIMARS system includes a launcher vehicle, resupply vehicle, and two resupply trailers.  This is space and volume that no ship has to spare.  Someone, at least, seems to recognize this.

“And then,” said O’Connor [Rear Adm. Cathal O’Connor, ESG-3 commander], “there is the question of trade-offs because ships are limited in volume, weight and personnel. So in order to bring X, we’d have to give up Y. So it’s something to consider.” (1)

That’s why the idea of placing trucks on the deck of an amphibious ship is silly.  The deck space is already completely accounted for and utilized.  Some essential function, like helos and MV-22s, would have to be sacrificed to accommodate the MLRS.

Further, a non-marinized HIMARS truck sitting out on the deck of a ship, subject to saltwater and the elements, will quickly corrode into inoperability.

Frankly, this stunt just smacks of more of the Marine’s recent trend to try to be and do all things instead of concentrating on its unique role and doing it well.

Now, the good news …  It appears that someone is at least thinking along the right lines.  As stated in many previous posts and comments, a MLRS system adapted to naval vessels is an outstanding idea.  The base system and munitions are already fully developed and in production with fully matured and understood costs.

The two main challenges to adapting MLRS to a ship are developing a naval launcher and writing code to allow the launcher to function on a constantly moving ship as opposed to the rock solid base of dry land.

Developing a permanent naval launcher, possibly a box launcher along the lines of the old Mk112 ASROC or the Mk29 Sea Sparrow launcher should not be that difficult.  We already know how to build both if we can resist the temptation to reinvent the wheel and gold plate it.

The software, or at least the basis for it, has already been developed, according to the article.

Having noted the stupidity of a truck on the deck of an amphibious ship, a viable alternative is a purpose built ship designed to operate MLRS launchers.  Such a system would possibly be a good fit for the LCS.  The ample flight deck and hangar space could be converted to launchers, magazines, reload mechanisms, and support mechanisms.  The resulting modified fire support LCS could be highly useful as a ground forces firepower support vessel.  Add in three or four SeaRAM launchers for self-defense and the ship would be well suited for close in fire support work.  There you have it – a useful purpose for the LCS!

Chinese Fire Support Frigate

The Chinese Type 053H frigate, Jiujiang, is an absolutely fascinating vessel for multiple reasons but the main reason is that the vessel was converted to a multiple launch rocket (MLR) fire support ship.

As a bit of background, the class was built in the 1970’s-1990’s and traces its lineage back to the Russian Riga class frigates. The vessels are around 330 ft long with a displacement of around 2000 tons.  Jiujiang was launched and joined the Chinese fleet in 1975 as a surface warfare frigate before being converted into a fire support ship in 2002.

The fire support modification consisted of 5x50-tube 122 mm (~5”) rocket launchers for a total of 250 rockets.  The rockets had a range of 20-30 km.  In addition, the ship retained its two dual 100 mm (~4”) guns.

That’s right, while the US Navy has abandoned fire support or offered an ill-conceived and now impotent Zumwalt and dithered about the possibility of mounting MLRS launchers on ships, the Chinese went ahead and did it.  This illustrates a few things:

  • The Chinese recognize the need for ship based fire support.

  • The Chinese are willing to construct/modify one-off prototypes to test and evaluate concepts.  While the US Navy has floundered around and largely ignored the issue of fire support, the Chinese built a fire support frigate, evaluated it, and are now retiring it.

  • The Chinese are willing to put older ships to use as test platforms.  Contrast this use of older vessels with the US Navy’s tendency to EARLY retire completely usable ships.

  • The Chinese were able to mount a LOT of firepower on a small, cheap vessel.  Contrast this with the US insistence on making every vessel big, expensive, and do-everything.  Also, contrast this vessel and its firepower density with the LCS’ near total lack of combat firepower.

  • The Chinese are far more open and nimble than the US Navy in terms of willingness to embrace change and the speed with which they build and experiment.

One cannot help but acknowledge that the Chinese are putting us to shame when it comes to prototyping, variety of designs, firepower density, speed of construction, and rate of technological advancement of their navy.  At this rate, we’re going to have to start hacking them to get their technology and designs!

We should also note that mounting rocket launchers on ships is hardly new.  The US Navy did it extensively in WWII, for example, but seems to have completely forgotten that capability just as they’ve abandoned fire support altogether.  If you’re interested, do an Internet search for LSM(R) to see what kind of rocket fire support vessels the US used in WWII.

The US Navy needs to look to the past while developing for the future and be more willing to construct one-off prototypes.  Older ships can be used for development purposes instead of being retired and sunk, scrapped, or sold.  The Navy and Marines need to continue to address naval fire support especially since the Zumwalt turned out to be a hideously expensive total failure.  We can learn a lot from the Chinese about how to develop a Navy!
