Inside the Navy has an article today called
Navy Looking at Potential Requirement for "Green Water" Vessel (subscription only) that discusses the Navy looking into a new ship class. This is the first time we have observed a two-star Admiral discussing a new ship class since the release of the 313-ship fleet.
“We’re contemplating a green water craft of some kind,” Rear Adm. Bruce Clingan said in a May 19 interview at the Pentagon. “That’s one of the things that we will explore” in the next Quadrennial Defense Review (QDR).
The concept is to field a ship for low-intensity conflicts, irregular warfare, increasing maritime security, and dealing with issues such as human trafficking while connecting with partners who have small navies for cooperative training. Specifically regions like the Gulf of Guinea in West Africa and Latin America are cited as locations where such a ship could have immediate impact to the maritime domain.
“We begin to speak to the green water requirement with [the] Littoral Combat Ship, but it’s a pretty big ship,” Clingan noted. The two LCS hulls under construction, one by Lockheed Martin and the other by General Dynamics, are over 300 feet long.
“There’s a rule of thumb, not scientific, that says a ship can coordinate well with another ship twice its size and half its size,” the admiral said. “And there’s an awful lot of our potential partners with ships from 45 feet to 150 feet. Do we need to look at a ship that’s somewhere around 100 feet, that’s cost-effective, that will help us build these meaningful partnerships working in conjunction with the Global Fleet Stations? Those are the types of things we have to consider as we move forward.”
As they plan for the future, Navy decision-makers are looking at the fleet and evaluating the utility of fielding an additional, smaller boat for use in places such as the Gulf of Guinea.
“To effectively build partnerships -- you know, an awful lot of our partners find it hard to work with a cruiser-size combatant capability -- one of the things in this 313-ship ‘floor’ that we’ll be looking at through the QDR process will be: Does the mix merit refinement? Do we have the right set of capabilities in these multimission ships?” Clingan explained. “This is an ongoing effort.”
What a Navy green water craft would look like remains unclear, the admiral said.
The article then turns towards a technical report released late last year from students at the Navy Postgraduate School called
A Systems Engineering Approach For Global Fleet Station Alternatives in the Gulf of Guinea. Is the Navy looking for a high-low mix for peacemaking? For those who haven't read the report, the GFS ship design calls for a ship between 5,000-10,000 tons with a draft of 15 feet or less, a top speed around 15 knots, a minimum 5,000 nautical mile range, and a crew of no more than 50 with additional berthing availability.
One aspect of the NPS report we found interesting is that it recommends and cites metrics why the LPD-17 class is the best existing platform for conducting this role if a new ship was not to be developed. Metrics for measurement included size, cargo-carrying capability, aviation and small boat capability, speed, communications, and command and control, which we find very interesting because with the exception of high speed, we have used the same measurements to describe the requirements for a large mothership.
Naturally we believe the developments being discussed are a move in the right direction, but it requires some critical thought prior to moving forward. While Global Fleet Stations is an important mission, and nobody on the internet has given more attention to Global Fleet Stations than we have, we observe there must be proper consideration for balance and alternatives built for
the Global Fleet Station design must justify the costs of peacemaking. An inexpensive armed 100 ft Corvette makes a ton of sense, but a 10,000 ton ship intended solely for peacemaking is a rather large investment that simply cannot be justified for the Navy unless it brings needed capabilities to the warfighter.
Is it possible the Navy is
reading and listening? While the NPS design is very interesting, in fact we like it a lot, we observe that major investments towards soft power must also scale towards a hard power profile to justify costs. For us, that means amphibious ships are the best investment for Global Fleet Station mission profiles, even if they aren't perfect for the role. We note that if the Navy can sustain the existing AEGIS fleet until 2020-2025 time frame, the shipbuilding budget is well positioned to invest in peacemaking over the next decade while also building redundancy and options for the joint warfighter in planning for a future challenger.
Should the cancellation of the DDG-1000 occur, the Navy could choose to take an interesting step towards aligning resources for the Maritime Strategy by moving up the
replacement date for the LSD(X) to now and building LPD-17s to fill that role. By doing so, the existing LSDs can then be utilized for the emerging requirements of motherships for unmanned combat systems and peacemaker roles including MDA and GFS. By using the existing 12 LSDs as motherships, this allows the Navy to go with an often discussed
Flower/
Fletcher model for small surface combatants, essentially a new 100 ft fast corvette and reuse the existing LCS hull for a fast frigate. While this may sound like a cost nightmare, it really isn't if you think about it. The Navy would essentially be trading the existing budgets for the remaining 5 DDG-1000s, 51 LCS, and the planned 12 LSD(X) for what amounts to 12 LPD-17s and a mix of frigates/corvettes.
The Navy would also have 8 of the existing LSDs as motherships until 2030, when the planned Littoral Combat Ships would start needing replacement anyway. This approach would ultimately save the Navy money in shipbuilding while allowing the Navy to use the 12 existing LSDs to further develop important 21st century strategic concepts, including Motherships, GFS, and MDA on a Sea Based platforms. By focusing all shipbuilding resources towards the small surface combatant, amphibious force, logistics force, and submarine force the Navy becomes well positioned to focus its shipbuilding budget to replace the existing large surface combatant force and SSBN force when that time arrives.
