Modernizing the Marine Corps Amphibious Landing Capabilities

Peter Lobner

Updated 7 January 2019 and 15 December 2020

1.  Introduction

The U.S. Marine Corps is taking a two-prong approach to ensure their readiness to conduct forcible amphibious landing operations: (1) modernize the fleet of existing Assault Amphibious Vehicles (AAVs), the 71A, and (2) select the contractor for the next-generation Amphibious Combat Vehicles (ACVs). The firms involved in these programs are Science Applications International Corporation (SAIC) and BAE Systems.

Both the existing Marine AAVs and the new ACVs are capable of open-ocean ship launch and recovery operations from a variety of the Navy’s amphibious warfare ships, such as a landing ship dock (LSD) or landing platform dock (LPD). These ships may be as much as 12 miles (19 km) offshore. After traveling like a small boat toward the shore, maneuvering through the surf line, and landing on the beach, the AAVs and new ACVs operate as land vehicles to deliver troops, cargo, or perform other missions.

The Marine Corps plans to maintain the ability to put 10 amphibious battalions ashore during a forcible landing operation.

Let’s take a look in more detail at the Marine Corps AAV 71A modernization program and the new ACV competition.

2.  The modernized AAV SU

The AAV SU is upgraded version of the existing, venerable Marine Corps AAV 71A, which can carry 25 embarked Marines. The AAV SU incorporates the following modernized systems and survivability upgrades:

  • armor protection on its flat underbelly
  • buoyant ceramic armor on the flanks
  • blast-resistant seats replacing legacy bench seating
  • new engine & transmission; greater horsepower & torque
  • improved water jets propulsors yielding higher speed at sea
  • external fuel tanks, and
  • upgraded vehicle controls and driver interface

In January 2016, SAIC unveiled the modernized AAV SU at its facility in Charleston SC and delivered the first prototype for testing at U.S. Marine Corps Base Quantico, VA on 4 March 2016. A total of 10 AAV SUs will be tested before the Marine Corps commits to upgrading its entire fleet of 392 AAVs.

Even after ACV deployment, the Marine Corps plans to maintain enough AAV SUs to equip four amphibious battalions.

3. The Next-generation ACV

On 24 November 2015, BAE Systems and SAIC were down-selected from a field of five competitors and awarded contracts to build engineering and manufacturing development prototypes of their respective next-generation ACVs. Both of the winning firms are offering large, eight-wheel drive vehicles that are designed to be more agile and survivable on land than the current AAV, with equal performance on the water.  The ACV is air-transportable in a C-130 Hercules or larger transport aircraft.

Under contracts valued at more than $100 million, BAE Systems and SAIC each will build 16 ACVs to be delivered in the January – April 2017 time frame for test and evaluation. It is expected that a winner will be selected in 2018 and contracted to deliver 204 ACVs starting in 2020. The new ACVs will form six Marine amphibious battalions that are all scheduled to be operational by the summer of 2023.

At the following link, you can view a Marine Corps video on the ACV program and its importance to the Marine’s “service defining” mission of making amphibious landings in contested areas:

BAE Systems ACV: Super AV

In 2011, BAE Systems teamed with the Italian firm Iveco to offer a variant of the Italian 8-wheeled Super AV amphibious vehicle to the Marine Corps.

The BAE version of this diesel-powered vehicle has a top speed of 65 mph (105 kph) on paved roads and 6 knots (6.9 mph, 11 kph) in the water. Its range is 12 miles (19 km) at sea followed by 200 miles on land. Two small shrouded propellers provide propulsion at sea. On land, the “H-drive” system provides power to individual wheels, so the vehicle can continue operating if an individual wheel is damaged or destroyed.

The armored passenger and crew compartments are protected by a V-shaped hull. Individuals are further protected from blast effects by shock-mounted seats.

On 27 September 2016, BAE Systems unveiled their 34-ton Super AV ACV, which normally will carry a crew of three and 11 embarked Marines, with a capability to carry two more for a total of 13 (i.e., a full Marine squad).

SAIC ACV: Terrex 2

SAIC partnered with ST Kinetics, which developed the Terrex amphibious vehicle currently in use by Singapore’s military. This vehicle currently is configured for a crew of three and 11 embarked Marines.

The basic configuration of SAIC’s Terrex 2 is similar to the BAE Super AV: V-shaped hull, shock-mounted seats and other protection for occupants, propeller driven in the water, independent wheel-driven on land, with similar mobility. SAIC’s Terrex 2 can reach speeds of 55 mph on paved roads and 7 knots (8 mph, 12.9 kph) in the open ocean. A Remote Weapon System (machine guns and cannon) and 10 “fusion cameras” allow closed-hatch missions with day/night 360-degree situational awareness.

7 January 2019 Update:  BAE won the ACV competition in June 2018

On 19 June 2018, it was announced that the Marine Corps had selected BAE to build the next generation Amphibious Combat Vehicle and a contract for $198 million for the first 30 ACVs had been awarded to BAE.  These vehicles are due to be delivered in the fall of 2019 for use in Initial Operational Testing & Evaluation (IOT&E). A decision to begin full rate production of the ACV is expected in 2020.

15 December 2020 Update:  BAE Set to Begin Full-Rate Production of the Marines’ New Amphibious Combat Vehicles 

In December 2020, the Marine Corps awarded BAE Systems a contract valued at almost $185 million to start full-rate production of the ACV and deliver the first 36 amphibious combat vehicles. BAE expects that this first-lot order will increase to 72 vehicles in early 2021.  In following years, the Marines have options to order 80 vehicles annually over five years.

Is Arthur C. Clarke’s 1953 Short Story “Superiority” a Parable for Today?

Peter Lobner

Sir Arthur Charles Clarke was a British science fiction writer, science writer and futurist who became recognized worldwide for his great many short stories and novels, which have captivated readers since the early 1950s. You might know him best as the author of “Childhood’s End” and “2001: A Space Odyssey.

In the short story “Superiority,” which was published in his 1953 story collection, Expedition to Earth, Clarke describes a spacefaring federation of planets involved in a protracted war with a distant adversary, with both sides using comparable weaponry. The allure of advanced weaponry and “a revolution in warfare” led one side to allocate their resources away from traditional weaponry and invest instead in fewer vessels with advanced weapons systems that were sure to turn the tide of the war: the Sphere of Annihilation, the Battle Analyzer, and the Exponential Field.

As you might guess, the outcome was somewhat different, because:

  • The new systems was “almost perfected in the laboratory”
  • There were unforeseen complications and delays during development of the operational systems
  • There were unforeseen support and training requirements that compromised the operational use of the new systems and introduced new vulnerabilities
  • The new systems failed to deliver the expected “force multiplier” effect
  • There were unforeseen consequences from the operational use of some new weaponry

The adversary won the war with a numerically superior fleet using obsolete weapons based on inferior science.

Bill Sweetman has written an interesting commentary on Arthur C. Clarke’s “Superiority,“ in the 14 March 2016 issue of Aviation Week and Space Technology. His commentary, entitled, “Timeless Insight Into Why Military Programs Go Wrong – The history of defense program failures was foretold in 1953,” finds stunning parallels between the story line in “Superiority” and the history of many real-world defense programs from WW II to the present day.

Considering SAIC’s long-term, significant role in supporting many U.S. advanced war-fighting and intelligence system programs, many of us were the real-world analogs of the thousands of scientists, engineers, and managers working for Professor-General Norden, the Chief of the Research Staff, in “Superiority.” In Bill Sweetman’s commentary, he asks, “Is ‘Superiority’ a parable?” Based on your own experience at SAIC and elsewhere in the military – industrial complex, what do you think?

If you still haven’t read “Superiority,” please do it now. It’s worth your time.
