The Marine Corps' version of the Jjoint Sstrike Ffighter's maiden deployment is set for late 2017 and its bound for the Western Pacific, the Navy's top officer in the Pacific said Tuesday.

The F-35B jump-jet stealth fighter will deploy aboard an amphibious flattop, enchancing its combat might, of the Navy's amphibious flattops and the service is planning a more powerful escort force to support it,  The Navy is testing out new fleet designs to expand the kinds of groups that can be sent downrange beyond the traditional carrier strike group model, and next year the Navy plans to test out a new configuration involving a big deck amphibious ship designed to haul Marines and their aircraft which includes the brand new F-35B,  according to Adm. Scott Swift, head of U.S. Pacific Fleet.

The F-35B was declared operational in July 2015 and testing continues ahead of next year's debut. PACFLT spokesman Lt. Clint Ramsden confirmed it would be the aircraft's first time to be based aboard a ship for a deployment, which typically lasts from a few months patrol up to an eight-month cruise. aboard ship.

A Attached to the group would be a surface action group, like the three-destroyer group dispatched mid-April to the Western Pacific, will defend the amphibious assault ship. made up of Spruance, Decatur and Momsen.

The concept was rolled out by Adm. Scott Swift during an April 26 all-hands call on the destroyer Momsen, which was docked in Hawaii on a port visit.

"I think this is going to revolutionize where we are with expeditionary strike groups," Swift said. "The three-ship PAC SAG that [destroyers] Decatur, Momsen and Spruance are part of will pave the way for another SAG, just like this one, attached to the large-deck amphib so that it will become what I'm calling an 'Up-Gunned ESG.'"

A typical ESG would includes an amphibious assault ship, a dock landing ship and/or amphibious transport dock and a couple of destroyers or a cruiser and a destroyer. An attack sub may would also likely accompany the group.

This new concept, with the addition of the joint strike fighter, looks a lot like a mini-carrier strike group. The surface action group envisioned by Swift would include a big deck and a handful of shooters.

Swift also said he has asked the destroyer squadron leader for the surface action group currently deployed to assign warfare commander responsibilities to the different ships and to act as if it were attached to the expeditionary strike group. The Decatur, which is a ballistic missile defense-capable ship, could take on the role of anti-air warfare commander, a role typically assigned to a cruiser.

"I'm excited about the potential options you will explore as part of this three ship SAG," Swift told sailors.

The SAG was deployed from Washington state and San Diego and was sent to be a test-case for new tactical concepts. the Navy is working on called "distributed lethality."

The idea is to concept is aimed at breaking up groups of surface combatants to threaten enemy ships and land targets from multiple angles and force the adversary to devote surveillance assets like submarines and aircraft to find them. The surface action groups pull the enemy in multiple directions and make it harder to target the carrier strike groups.

The up-gunned ESG takes that approach a step further and creates even more problems for an potential adversary when you add the F-35B, which has a significantly longer range than the current AV-8B Harrier,s which is a mainstay of the Marines' ground-attack mission. the current mainstay of the Marine air wing. Like the Harrier, though, The F-35B will be able to take off vertically. It's the version that the Royal Navy plans to put on its new class of carriers, rather than the F-35C that features a tailhook.

An up-gunned ESG could also help alleviate some of burden on the overstretched flattop fleet, though the amphibious assault ships will only pack six to eight F-35s, said Jerry Hendrix, a retired naval aviator and analyst at the Center for a New American Security. That's compared to roughly 40 jets on an aircraft carrier.

"This is a step forward in the right direction," Hendrix said. "What Adm. Swift is doing is tuning the force to get the most out of it, and that's important given the carrier shortage we have right now. It also shows the scalability of the force to meet different demands."

Seth Cropsey, head of the Hudson Institute's Center for American Seapower, agreed it was a step in the right direction but that the concept was still large and expensive for low-to-mid-range missions.

"If we want ESGs to fight smaller brush fires to leave the carriers to larger conflagrations, that's fine but it's still expensive," Cropsey said. "The F-35B is not something you buy in your local CVS."

The Navy is still trying to find the right way to use its high-tech and expensive force that regularly gets called to do low-end missions such as counter-piracy and disaster relief, Cropsey said.

"They are still adjusting the dials and come up with something that handles both large-scale warfare — and in the Western Pacific that means China — and the lower order things like [humanitarian assistance, disaster relief]. I don't think the up-gunned ESG is the end of the line, and I don't think PACFLT thinks it's the end of the line either."
