Hi-Lo, War-Peace

Discussions of the LCS, missile boats, green water combatants, and even frigates ultimately lead to a discussion of the roles these vessels ought to play within the Navy.  Inevitably, the roles resolve into one of two broad categories:  high end combat or peacetime presence.  The discussion is further complicated by the fact that many of the requirements for either category are not needed for the other and only increase construction and operating costs for no gain in performance.

For example, a notional smaller combatant, let’s say a beefed up LCS or a true frigate would have sophisticated sensors, combat systems, VLS, etc. – none of which are necessary for peacetime presence tasks.  They simply add cost to a vessel that is only required to show the flag, cross-train with foreign small navies, perform boardings and inspections, dissuade pirates, host dignitaries, and so forth.  They add no useful functionality for the peacetime tasks.

On the other hand, a vessel designed for peacetime tasks would have a basic sensor suite, 25 mm – 76 mm weapons, a basic RAM or CIWS self defense fit, RHIBs, and perhaps a small UAV.  While quite adequate for peacetime activities such a vessel would be only marginally useful (as in not useful) in a high end combat scenario.

Of course, we can build ships that are capable of fulfilling the roles in both categories.  A Burke is expected to be our main surface combat vessel of the future and is certainly capable of carrying out any peacetime presence task.  The problem is that the Burkes are very expensive and we can’t afford to build them in the quantity required to meet all the peacetime missions.

In the past, we tried to span the two categories by building a Hi-Lo mix of ships.  That effort gave us the Perry FFG’s.  While very useful ships and moderately affordable, the ships were oversized and over spec’ed for peacetime tasks and barely adequate for combat (under the right circumstances).  In other words, the Perry’s were a less than optimal fit for either category.  Thus, the Hi-Lo mix program, while not a failure by any means, was not a complete success, either.

I think the Hi-Lo mix concept was in the neighborhood of correct but missed the mark by trying to straddle the line between the two categories.  The concept compromised the needs of both categories while increasing costs.  What’s needed is not a Hi-Lo mix but, rather, a War-Peace mix. 

Instead of trying to straddle the line between War and Peace, we need to build a mix of ships that are optimized for one or the other category.  Let’s build peacetime vessels with the aforementioned minimal equipment fits required to carry out the peacetime presence tasks.  Let’s build combat vessels that are intended to fight.  When war comes, the Peace vessels would step out of the way.  When War comes we’ll let the optimized combat vessels do their job.  During peace, which is most of the time, the combat vessels, no longer needed for peacetime tasks since we’d have a fleet of peacetime vessels, could largely revert to “garrison” status and focus on maintenance and combat training.  This would markedly extend the life spans of these ships and produce a fleet with a greater degree of readiness.

Of course, the main characteristic of the Peace side of the mix is numbers.  Numbers, in turn, implies affordability.  This should be readily achievable since the vessels won’t need high end combat systems and would have no need to be built to any significant survivability standard.  They would be not much more than civilian vessels with a bit more sensing and a rudimentary self-defense capability. 

Further, since the ships would not need to be built for any function beyond the intended peacetime tasks, they should be able to be significantly smaller.  A Cyclone patrol vessel, for example, could handle the vast majority of peacetime tasks and a handful of larger, Coast Guard-ish vessels could handle the slightly more demanding tasks.  Regardless, the average vessel size ought to be quite small compared to frigates or corvettes.

In addition, the crews could be downsized a bit since, by definition, there would be no need for damage control or significant battle station manning.

Now, here’s an interesting thought.  If we had a peacetime fleet and a combat fleet we might be able to utilize the peacetime fleet crews in the combat vessels when war comes since the peacetime vessels would be set aside, anyway.  Of course, we’d have to rotate the peacetime crews through the combat fleet during peacetime but, given that the combat fleet would be fully focused on training, there would be plenty of opportunities.  Thus, we might be able to operate two fleets with only one fleet worth of manning.  Of course, I don’t mean that literally.  The combat fleet, even in a “garrisoned” status, would require additional crews.  Further, some combat functions can’t just be occasionally trained for – some, such as ASW, require constant, intense training to acquire and maintain proficiency.  Still, the concept of shared manning has validity to some extent, probably significantly so.

ComNavOps has expressed dissatisfaction with the NNFM force structure due to its emphasis on green water combatants that are neither combat worthy nor peacetime efficient.  This alternative, then, offers the possibility of merging the two concepts into a single, affordable force structure which formally recognizes the inherently contradictory roles, peace and war, that the Navy is tasked with.  As I so often say, it’s worth some consideration given that the path the Navy is currently on is unsustainable.

Green Water Combatant

Recent posts and discussions about Hughes small combatants and The New Navy Fighting Machine (NNFM) have inspired a lot of conversation about so-called green water combatants.  These are small ships of a few to several hundred tons, depending on the particular version under consideration, and generally heavily armed, for their size, with missiles and guns.  Unit costs are typically estimated as being very low, perhaps unrealistically so. 

Now, before anyone starts typing out a reply purporting to show that Elbonia can build supercarriers for $19.95 or whatever your favorite example of a small combatant and the associated country is, remember that trying to obtain true cost numbers for US ships is virtually impossible and trying to compare costs between countries is pointless for a host of reasons.  Further, it doesn’t matter what Elbonia can build ships for – it only matters what the US can and the US Navy has not demonstrated the ability to build anything cheaply.

Moving on …  The NNFM document offers this general description of small, green water combatants.

Coastal combatants are heavily armed, but small enough to accept affordable losses. They should operate in tactical formations of two, four, eight, or twelve vessels. They carry no surveillance aircraft, so depend on CVLs or shore-based reconnaissance. They have small crews in combat and when put out of action the crew is expected to abandon, rather than try to save, the ship, and to be rescued by other vessels. They might team with friendly forces in constricted waters where the large blue water ships should not be put at risk, for example, operating from Turkey or Romania in the Black Sea, from Sweden or Denmark in the Baltic, from Saudi Arabia or Kuwait in the Arabian Gulf, from the west coast of South Korea in the Yellow Sea, or Colombia or Panama in the Caribbean.

They can serve as an advance force to screen blue water ships conducting amphibious operations, or protecting MSC (Military Sealift Command) or MARAD ships delivering men and materials that might be attacked while entering a friendly port.”

Well, that’s a pretty decent description of the kinds of uses proponents envision for them.  The problem is that most discussion of green water combat is conceptual and fails to incorporate any realistic assessment of threats.  By that I mean that the discussion describes the theoretical abilities of the ship without questioning whether there is any likelihood that those capabilities would actually be needed.  For instance, stationing ships in the waters of Sweden or Denmark or Colombia  or Panama or Philippines or wherever glosses over the fact that it is highly unlikely that any combat would there that would be appropriate for such a vessel. 

Consider the likely near term (because the vessel’s would have relatively short life spans) scenarios.

Iran is a likely point of conflict but the waters off Iran would see high end combat with massed missiles and aircraft on both sides.  This is not a green water combat scenario.

N. Korea is a likely point of conflict but there would be little need for green water combat.  N. Korea has no significant green water fleet that would need to be dealt with and the US would have massed carrier groups and submarines on site anyway.  This is not a green water combat scenario.


China is a possible point of conflict but China’s goals for the near term would be focused on Taiwan.  Seizure of the first chain islands would be an unlikely afterthought.  The US, if it responded, would mass carrier groups and submarines.  This is not a green water combat scenario.

Africa offers points of conflict but the conflict would be land based against terrorist groups.  This is not a green water combat scenario.

Consider escort duties - supposedly another likely scenario.  Under what circumstance would ships need escort but only from a low level threat?  High level threats would necessitate high level escorts.  The escort scenario devolves into an anti-piracy type of role which any vessel with a machine gun can do.  It wouldn’t require a specialized green water combatant.

The NNFM suggested the need for host country basing for the green water fleet.  OK, that’s reasonable but what friendly country (friendly enough to grant us basing rights) is likely to be attacked by a low level threat that would justify stationing green water combatants there?

In short, the likely conflicts and proposed uses do not offer a reasonable real world green water combat scenario.

Now, this does not say that there would be absolutely no use for a small number of green water vessels but they would be used in peacetime patrol roles and certainly would not justify shifting the emphasis of the US Navy to a green water focus as the NNFM suggests.  I find the NNFM’s green water emphasis to be conceptually and generically valid but devoid of demonstrable real world need.

If you want to debate this with me (and you know you do!), tell me what real world location you’d send green water combatants to and what real world threat they would be countering.  Hey, I’m open to the concept if it serves a real purpose.  If you think you have one, tell me.  I’ll acknowledge it if it’s valid.
