The Marine Corps is looking to plus up the firepower aboard its new amphibious combat vehicle with a 30mm cannon.
Officials with Marine Corps Systems Command posted a request for information on the government website FedBizOpps on Monday. The ACV will replace the aging assault amphibious vehicle, which entered service in the early 1970s.
The Marines want three variants of the ACV ― a command and control configuration, a recovery and maintenance setup and ACVs with 30mm medium-caliber cannons.
The older AAV had space for a 40mm grenade launcher, but in direct vehicle-on-vehicle fighting the 30mm cannon offers fast, high-volume direct fire.
BAE Systems was selected in 2018 to produce the ACV, which is expected to reach initial operational capability by fiscal year 2020. The company has built amphib vehicles for the military since 1941.
The ACV is a chief “connector” from ship to shore for Marine amphibious operations. it will include mine resistant ambush protected-level armor, and able to “negotiate two-foot significant wave height and four-foot plunging surf,” according to Program Executive Office-Land Systems.
The 30mm-cannon arming follows suit with making existing and future ground combat vehicles more lethal. The Army began upgunning its Stryker vehicles with a 30mm cannon, replacing its twin .50-caliber machine guns.
In 2018, the Army also put in place the common remotely operated weapon station for the Javelin missile on the Stryker, keeping soldiers inside the vehicle when firing the missile.
Those upgrades began first in Germany as a counter to increased capabilities in the Russian ground formations.
The Marines have also started upgrading their light armored vehicle, also a decades-old platform, to include a better powerpack, drive train and digitized instrument panels.
Late last year the Corps was still only looking at two ACV variants, according to official postings: the turreted assault vehicle and the command and control version.
At the annual Modern Day Marine Military Expo at Quantico, Virginia, John Swift, program director for BAE's amphibious vehicles, told Marine Corps Times that they expect to have 30 vehicles built by the end of summer 2019 to go through testing and modifications as the Corps decides the composition of the ACV fleet. Those will be basic testing platforms.
This most recent posting gives some indications of what the Corps needs.
Most recently the Corps was asking for 704 ACVs when full production begins in 2022. Those are expected to be done within six years.
And a previously ongoing contract with another company to perform survivability upgrades on an estimated 392 AAVs was cancelled last year in a move of funding from that program to more rapid modernization priorities.
The legacy AAV is a tracked vehicle, while its replacement will be an eight-wheel vehicle.

A sweeping set of proposals could comprise one of the Department of the Air Force's most significant reorganizations since the end of the Cold War.

By: Beth Stevenson RAF FAIRFORD, England — General Atomics Aeronautical Systems' developmental MQ−9B SkyGuardian made the first ever transatlantic flight of a medium-altitude, long endurance aerial drone. The unmanned aerial vehicle completed touched down at RAF Fairford in the United Kingdom after a 3,760 nautical mile sortie from the U.S. July 11 that began at the Grand Forks test site in North Dakota 24 hours and 2 minutes prior. The journey was the first transatlantic flight of both the SkyGuardian and any MALE UAV, but also the first U.K. appearance of the UAV that the Royal Air Force will operate under its Protector program. The U.K. is the launch customer for SkyGuardian, and the journey to RAF Fairford to take part in the Royal International Air Tattoo (RIAT) ties in with the RAF's centenary celebrations, as the MQ−9B will be one of the next combat aircraft types delivered to the service. L3 Technologies Communication Systems provided Ku-band satellite communication (SATCOM) to control the UAV throughout the flight with no handover to a control station in the U.K, although Inmarsat Government provided a backup L-band SATCOM capability in case of failure. A line-of-sight ground control station was shipped to Fairford and was responsible for taxiing the aircraft once it had carried out its automatic landing. It flew at approximately 27,000 feet for most of the flight, dropping to 9,000 feet and maintaining a holding pattern near Fairford for some 2 hours ahead of landing, transiting initially via Canada, over to the South of Ireland, and then over Wales before reaching its end destination. Jonny King, vice-president of GA-ASI UK, told a media briefing at Fairford that the transit demonstrates that the UAV is self-deploying, and the journey was relatively routine for the test aircraft — just with a different landing destination. It has previously flown a sortie of more than 48 hours, King noted, and for the transatlantic flight it was able to fly under the U.S. Federal Aviation Administration's authorization, with support from the U.K. Civil Aviation Authority that granted an overflight permission for the transit into U.K. airspace. While the U.K. is on record as being the launch customer for the SkyGuardian through its Protector effort, the aircraft is yet to go through certification testing — one of the most distinguishing features of this variant — and will not be delivered to the RAF until the early 2020s. Development and certification contracts for Protector have been signed, but a production contract for the buy is not expected to be signed for some time, the RAF told Defense News. Air Marshal Julian Young, chief of materiel for air, defense equipment and support for the RAF, said that it is expected that Protector will be acquired under two direct commercial sales contracts and two foreign military sales deals with the U.S. government, covering the various elements of development and acquisition. “Protector is one of the most exciting projects I have to deliver,” Young said, adding that it will be a “gamechanger” in its ability to fly alongside manned aircraft under the remit of air traffic control, with the ultimate goal of being able to fly in open airspace alongside uncontrolled aircraft. “This is a key component of the future of the RAF's air power,” he told media at the aircraft landing event. “I hope this is going to set the standard for aviation. The U.K. is very happy to be the lead with this unique capability.” SkyGuardian has been in test flight for some 18 months so far, King said, adding that the second test aircraft – YBCO2 – will join the first aircraft in test flight in the next month or so. In accordance with the U.K.'s 2015 Strategic Defence and Security Review, the RAF will more than double its MALE UAV capability, which is currently fulfilled by a fleet of 10 Block 1 MQ-9 Reapers, so as few as 21 could be acquired, although 26 is a figure that has been previously touted. The RAF has claimed that integrating UK-made weaponry is a priority for the program, so it will operate MBDA's Brimstone ground attack missile and Raytheon UK Paveway IV laser-guided bombs, although contracts for these have also not yet been signed. “Sovereignty is clearly an important issue,” Young told Defense News, adding that while the Reapers that were bought in the same configuration operated by the U.S. Air Force have been a capability that the U.K. has been able to effectively exploit, more sovereignty would have been an advantage. But “this comes at a cost.” He added that the training capability that the U.K. will use is still undecided on, although the U.K. is open to this taking place domestically or with other partners should another nation elect to acquire aircraft. SkyGuardian will be showcased throughout RIAT before being dismantled and shipped back to the U.S. a week later, King noted. https://www.defensenews.com/digital-show-dailies/riat/2018/07/13/gamechangeraerial-drone-arrives-in-uk-after-mammoth-24-hour-transatlantic-flight/?utm_source=Sailthru&utm_medium=email&utm_campaign=ebb%2016.07.18&utm_term=Editorial%20-%20Early%20Bird%20Brief
