  • Is the US Navy winning the war on maintenance delays?

    Is the US Navy winning the war on maintenance delays?

    David B. Larter WASHINGTON — The U.S. Navy, beset by maintenance delays, is making progress on getting its ships out of the shipyards on time, fleet officials say. Over the past three years, the Navy is on track to more than double the percentage of ships getting out of maintenance on time, key to the service's efforts to make deployments more sustainable for its ships and sailors, Capt. Dave Wroe, U.S. Fleet Forces Command's deputy fleet readiness officer told Defense News in an email. “On-time ship maintenance availability completion rates in private shipyards improved from 24% in FY18 to 37% in FY19,” Wroe said. “Current performance trends in FY20 are projected to be 65%.” The improvement is a sign that the Navy may be turning the corner on a fight to restore readiness from its nadir in the early part of the last decade, when the Navy was running ragged filling unsustainable requirements for forces around the globe. Getting ships through their maintenance cycles on time is the linchpin of what the Navy calls its “optimized fleet response plan,” which is the system through which the Navy generates deployable ships that are maintained, manned and trained. Late last year and again in January, Chief of Naval Operations Adm. Michael Gilday told audiences that repeated delays in the shipyards was undermining the Navy's Optimized Fleet Response Plan, and turning that around was vital. “We are getting 35 to 40 percent of our ships out of maintenance on time: that's unacceptable,” Gilday said at the USNI Defense Forum in December. “I can't sustain the fleet I have with that kind of track record.” A recent Government Accountability Office report found that between 2015 and 2019, only 25 percent of the Navy's maintenance periods for ships and submarines. Improvements Getting out of that hole has been difficult for a number of reasons: High operational demand for Navy forces makes planning maintenance difficult, and inevitably when the ships go into maintenance after years of hard use, workers discover more work that needs to be done, creating delays. And those delays make executing OFRP difficult, Wroe said. “OFRP provides the construct to best assess and optimize readiness production — down to a unit level — taking into account all the various competing factors to produced Navy readiness,” Wroe said. “Bottom line: OFRP helps mitigate fundamental points of friction, such as shipyard capacity and manning gaps at sea — but in itself doesn't solve key degraders like depot level maintenance delays and extensions.” But some key factors in the delays have been identified and the Navy is working to mitigate them, Fleet Forces Commander Adm. Chris Grady said this week at this week's Fleet Maintenance and Modernization Symposium. One area that has a tendency to drive delays is when workers discover things that need to be fixed, the fix may not cost much but the adjustment must go through an approval process that slows everything down. Those kinds of changes add up to about 70 percent of the so-called “growth work.” Part of it is anticipating and building in ways to deal with growth work into every maintenance period, and the other part is making it easier to address small changes to the scope of the work, Grady said. “When we began this initiative, cycle time for the small value changes averaged about 30 days,” he said “We're now at six and aim to bring it down further to only two days.” Other things that have helped the problem has been bundling maintenance periods for ships, meaning that contractors bid on multiple ships to fix, and can plan hiring further out, Grady said. Additionally, improving base access for contractors has helped, as well. “Last year, we averaged 110 days delayed per ship in private avails,” Grady said, using the short-hand term for “maintenance availability.” “Things much better this year — even with COVID-19,” he continued. “We go from about one-third avails finishing on-time to two-thirds. That is great. But, again, each delay has real impact on our readiness, and we need to keep working together to do better.” What happened? Because the U.S. Navy is set up to meet standing presence requirements and missions around the world, it must cycle its ships through a system of tiered readiness. That means ships go on deployment fully manned, trained and equipped. Then the ships come home, and after a period of sustained readiness where the ship can be redeployed, it goes into a reduced readiness status while undergoing maintenance. Following maintenance, the ship and crew goes into a training cycle for another deployment as an individual unit, then as a group, then returns to deployment. The whole cycle takes 36 months: Rinse and repeat. OFRP was designed in the 2013-2014 time-frame when the Navy was deploying well beyond its means, with carrier strike groups and amphibious ready groups going out for nine-to-10 months at a time. The excess use wore hard on the ships and sailors who manned them and put more wear on the hulls than they were designed to sustain. That meant that when ships went in for maintenance they were more broken than they were supposed to be, and funding to fix them was hampered by spending cuts. For nuclear ships — submarines and aircraft carriers — the funding cuts were a double whammy of work stoppages and furloughs that contributed to a wave of retirements in the yards, meaning the public yards were understaffed and had to hire and train new workers. Work took longer, throwing a wrench into an already complicated system of generating readiness. All that added up to significant delays in getting ships through their maintenance cycles and contributed to astonishing delays in attack submarine maintenance especially. What OFRP was meant to do was create a system whereby the Navy could meet combatant commander demands but not break the system. That meant that the Navy would generate as much readiness as it possibly could but that the demand would have to be limited to what the Navy could reasonably maintain, man, train and equip. But getting to that system has been immensely difficult because of the deep hole the Navy dug meeting requirements that well outstripped funding and supply. For example, there was a two year period when the service was forced to supply two carrier strike groups to the Arabian Gulf at all times, a requirement only canceled when automatic across-the-board spending cuts in 2013 made it impossible for the Navy to fund the two-carrier requirement. Adding to the difficulty: some of OFRP's founding requirements were nigh impossible to pull off. One was that the all the ships in group would go into and come out of their maintenance availabilities on time and together. Another was that a group would go into the first phase of their training, the so-called basic phase right after coming out of maintenance, fully manned. Both have been immensely difficult to pull off. But Fleet Forces, headed then by OFRP architect Adm. Phil Davidson, was given ample warning that those assumptions would be difficult to achieve. Then-NAVSEA head Vice Adm. William Hilarides told USNI News in January 2015 that getting ships to come out of the yards simultaneously would be hard. “The challenge to me is, let's say you want four destroyers in a battle group, all to come out at the same time in one port? That's a real challenge,” Hilarides told USNI News. The current head of NAVSEA, who at the time was in charge of the Regional Maintenance Center enterprise, backed up his boss to USNI News, saying it would be particularly challenging in places with less infrastructure. “Your big rub there is, the challenge of OFRP is ... all those ships [in a carrier strike group], they go through maintenance together, they go through training together and they deploy together,” said then-Rear Adm. William Galinis. "So, what our challenge is, is to be able to take all that work from all those ships and try to schedule it for roughly about the same time, and to get all that work done on time. So that's our challenge. “Now, in a port like Norfolk or San Diego, we have big shipyards, a lot of people, a lot of ships. You can kind of absorb that type of workload. When you go to Mayport, they've got like 10 ships down there [and typically cannot work on more than one or two destroyers at a time.],” he told USNI. Galinis said that Fleet Forces would have to be responsive to the shipyards because at least that way they could plan for delays. “They know if they give us all this work at one time, it's going to go long anyway,” he told USNI. “So they'd rather be able to plan that and at least know when they're getting the ship back, as opposed to, ‘nope, we're not going to talk to you, you've got to go do it,' and then the ships go long because we don't have enough people to do the work.” Fleet Forces Command has been reviewing its assumptions this year and is preparing to release a revised OFRP instruction, but the core is likely to remain the same. In any case, Wroe said in the email, it was always going to take a long time to dig out of the hole the Navy found itself in when OFRP was implemented fully in 2015. “It was clear at the inception of OFRP, and remains clear today, that it will take the entire 2015-2025 period to recover readiness and establish stable readiness production,” Wroe said. “That makes sense when readiness production is planned over 9-years and large blocks of time have already been scheduled for depot maintenance periods.” Ultimately, if the process of OFRP is funded correctly and ships can get out of maintenance on time, it's a sound way of moving forward, Fleet Forces Commander Grady told the audience this week. “My bottom line here is that, as a process, OFRP works,” he said. “If we are looking where to improve upon it, each of these studies came to the same conclusion: the biggest inhibitor to fleet readiness is maintenance and modernization performance in the shipyards. We simply must get better, and I know you share my concern.” https://www.defensenews.com/naval/2020/09/19/is-the-us-navy-winning-the-war-on-maintenance/

    Textron Preps For Mass Production Of New Army Rifle

    By SYDNEY J. FREEDBERG JR. WASHINGTON: Textron has partnered with global gun-maker Heckler & Koch to mass-produce new rifles for the Army and with ammunition giant Olin Winchester to churn out the high-powered yet lightweight 6.8 millimeter rounds. Textron still has to beat both General Dynamics and Sig Sauer for the right to build the Next Generation Squad Weapons (NSGW). All three companies won awards last Thursday to build prototypes for troops to test, starting this coming spring and continuing through late 2021. No follow-on production contract is guaranteed. But Textron is watching the Army's urgent push to modernize across the force, from assault rifles to hypersonic missiles and wants to be ready to sprint to mass production if it wins. Textron could do everything in house, senior VP Wayne Prender said. But, he told reporters this morning, by working with Olin Winchester and H&K, which are experienced with largescale manufacture of ammo and weapons respectively, “we are preparing ourselves for a high rate of production.” The Army wants to start fielding two variants of NGSW to tens of thousands of close combat troops — infantry, scouts, special operators, and so on — in 2022. Support troops and vehicle crews will stick with the current M4 carbine for the indefinite future. But frontline ground combatants will get more than just a gun. Linked wirelessly with electronics all over the soldier's body, including Microsoft HoloLens-derived targeting goggles called IVAS, the Next Generation Squad Weapon is meant to be just one lethal component of a larger, high-tech system. It's like the Hellfire missiles on an Apache helicopter or the 120 mm Rheinmetall smoothbore cannon on an M1 tank, except this “weapons platform” moves on foot. This approach is part of a wider push, begun by former Defense Secretary (and Marine Corps rifleman) Jim Mattis, to improve the Close Combat Lethality of the military's most exposed members. The American grunt has accumulated more and more high tech over the last two decades. Designing a new weapon from scratch is a chance to streamline the scopes, cables, batteries, and other impedimenta festooning modern foot troops. “All of those are now part of an integrated weapon system, versus a rifle that then has something else strapped onto it with wires hanging off,” Prender told reporters. “We can make some smart decisions early in the design process that enable it to be cleaner.” That should make the new weapon easier to use, lighter, and even better balanced, since the center of gravity is now calculated with installing add-ons in mind. Three Contenders, 27 Months While troops will test the first prototypes this spring, each contender has 27 months to deliver a total of 53 NGSW assault rifles — potential replacements for the M16/M4 family in service since Vietnam — and 43 automatic rifles — replacing the M249 SAW — along with 850,000 rounds of 6.8 mm ammunition. Like the M16, M4, and M249 with the 5.56 mm cartridge, the new NGSW family will all share a common 6.8 mm round, which is supposed to deliver longer range and greater body-armor-penetrating power without increasing weight much. Each competitor has their own spin on how to deliver the new rifle bullet. Sig Sauer, which already builds the Army's standard 9mm pistol and a host of other limited-issue weapons, has taken what seems to be the most conservative approach. It offers what the company calls a “hybrid” cartridge, which is still made of metal like traditional brass casings, but significantly lighter. General Dynamics's Ordnance & Tactical Systems (OTS) division has partnered with a Texan firm, True Velocity, to build “composite” rounds out of polymers. In layman's words, the bullet is packaged, not in brass, but rugged plastic. Again, the goal is to save weight. Textron's approach is arguably the most radical, to the point it doesn't even look like a bullet, just a cylinder that's equally blunt on both ends. That's because it's a cased telescoped round, sheathing the entire bullet in a polymer shell, surrounded by its propellant instead of sitting on top of it. (The resulting case looks like a folded-up telescope, hence the name). Textron says this method cuts weight per shot by 40 percent, a potential boon for overburdened foot troops. The Army's new modernization strategy — after decades of cancelled programs and incremental changes to aging weapons — is to try such great leaps forward but then test prototypes ASAP with real troops in the field. The service has been “opening the doors of the Army to the contractors to get that feedback early and often,” Prender said approvingly. Each round of user feedback is meant to help the contractors improve their product, and the military to refine their specifications, until the service can confidently choose a refined design. Now, the Army isn't locking itself in. Whoever does best in testing, the Army hasn't promised the winner a production contract. But Textron is betting they can convince an eagerly modernizing Army that their product is not only superior but ready to field without further R&D. “Whether [to] move right into an initial Low-Rate Initial Production, followed by fielding and first unit equipped, or [to do] additional prototyping and maturation of the weapon system... all that will be determined by the Army,” Prender told reporters. “We have high confidence that our weapon system will meet all of the requirements that the Army has laid out... so we're looking forward to at the end of those 27 months to move into production.” https://breakingdefense.com/2019/09/textron-readies-for-mass-production-of-new-army-rifle
