FREDERICKSBURG, Va. – Army leaders see a future battlefield with networked minefields a commander can see from across the globe through satellite communications and that can be scattered in minutes but also retrieved and reused when needed.
The push is an effort to keep landmines of various types in the weapons portfolio while still meeting the agreements made to get out of the old school “dumb” landmine use.
Smart mines being developed now are a way to replace some of the aging stocks in the “Family of Scatterable Mines” run by the Army's Program Manager Close Combat Systems.
The program actually runs nearly half of all munitions from non-lethals to hand grenades to shoulder-fired rockets and counter explosives equipment.
The portfolio, its challenges and what's happening now were laid out for attendees at the annual National Defense Industrial Association's Armament Systems Forum in June.
Top of the priority lists are some simple munitions needs — more hand-grenade fuzes and better shoulder-fired weapons.
But the big ticket items that need problem solving are how to use “terrain shaping obstacles,” or landmines, that can be delivered to close, middle and deep distances and then controlled to avoid the problems of scattering mines across war zones and then leaving them for an innocent passerby to trigger years or decades later.
Small options such as the remote activation system used for current mine emplacements relies on radio frequency transmissions.
But, as Pelino noted, in a near peer fight it's likely that adversaries will do RF jamming.
The Army has a host of terrain-shaping obstacles, everything from the trusty standby Claymore mine which came online in the late 1950s and saw extensive use in the Vietnam War to the Gator system, which can be air dropped to take out everything from an individual soldier to a tank.
They're also the anti-personnel area denial artillery munition, or ADAM, mine that can be launched using a 155mm round from artillery. Its cousin, the remote anti-armor munition, or RAAM, packs a bit more of a punch but also can be delivered from anything that fires a 155mm shell.
Both are fired to the area of the threat and then roll out multiple mines that detonate when the appropriate level of vibration triggers them.
Pelino described the Modular Pack Mine System, or MOPMS, like a minefield in a suitcase. Though coming in at 165 pounds, that's a very heavy suitcase. A single radio-control unit can run up to 15 MOPMS on the battlefield. They can also be hardwired to a controller.
An upside to the MOPMS is it can be recovered and reused.
On the lighter side is the M86 pursuit deterrent munition. It was designed for special operations forces to use when being pursued by an enemy. Think classic films where the character scatters nails or an oil slick to slow down their chaser, except with a lot more boom.
Only instead of firing from a cannon, the soldier has to arm the device and deploy tripwires for bad guys to stumble upon.
The Volcano mine system takes more of an industrial approach. Allowing a UH-60 Black Hawk to create a 1,000-foot minefield in less than a minute, Pelino said.
The problem with all of those systems is they don't currently meet treaty obligations and many that had about a 20-year shelf life are pushing past 30 years now.
Most will still be in stock at 2035, as the Army uses updates to keep them serviceable, Pelino said.
The newer Spider System is one that allows soldiers to put in a porcupine-looking system that gives 360-degree coverage to deny enemy access to an area while also networking with other systems and a common controller.
Future systems will look a lot more like Spider and a lot less like pressure plate mines of the World War II era or the venerable Claymore.
The future minefield systems must have a 2 to 300km communications capability, an ability to be switched on and off, remotely modified self-destruct or deactivate mechanisms, self-report status so that users will know if they've been tampered with or if a mine went off.
The Army also wants the mines to be able to not just blow up when something rumbles by but also detect, track and engage threat vehicles for everything from tanks to engineer equipment. Oh, and it must work in all terrain and weather conditions, be easily trained and employed, recoverable, reusable and affordable.
The standard kit will include between half and a full brigade's worth of mines to block off areas for maneuver and prevent enemy flanking.

The U.S. State Department has approved the potential sale of an Integrated Air and Missile Defense Battle Command System to Poland for an estimated cost of $4 billion, the Pentagon said on Monday.

By: David B. Larter WASHINGTON – The Department of Defense has sent a plan to the White House that would cut the construction of more than 40 percent of its planed Flight III Arleigh Burke destroyers in in fiscal years 2021 through 2025. In total, the proposal would cut five of the 12 DDGs planned through the so-called future years defense program, or FYDP. In total, the plan would cut about $9.4 billion, or 8 percent, out of the total shipbuilding budget, according to a memo from the White House's Office of Management and Budget to the Defense Department obtained by Defense News. The memo also outlined plans to accelerate the decommissioning cruisers, cutting the total number of Ticonderoga-class cruisers in the fleet down to nine by 2025, from a planned 13 in last year's budget. The Pentagon's plan would actually shrink the size of the fleet from today's fleet of 293 ships to 287 ships, the memo said, which stands in contrast to the Navy's goal of 355 ships. The 355 ship goal was also made national policy in the 2018 National Defense Authorization Act. The memo comes on the heels of a wave of rhetoric from the Navy and the highest levels of the Trump Administration that the goal remains 350-plus ships, and the memo directs the Pentagon to submit a “resource-informed” plan to get to 355 ships, though its unclear how that direction might affect the Navy's calculus with regards to destroyer construction. The document gives the Navy a degree of wiggle-room to try and redefine what counts as a ship. “OMB directs DOD to submit a resource-informed plan to achieve a 355-ship combined fleet, including manned and unmanned ships, by 2030,” the memo reads. “In addition to a programmatic plan through the FYDP and projected ship counts through 2030, DOD shall submit a legislative proposal to redefine a battleforce ship to include unmanned ships, complete with clearly defined capability and performance thresholds to define a ship's inclusion in the overall battleforce ship count.” Destroyers are built by General Dynamics Bath Iron Works in Maine and by Huntington Ingalls in Pascagoula, Mississippi. Each destroyer costs an average of $1.82 billion based on the Navy's 2020 budget submission, according to the Congressional Research Service. A Trump Administration official who spoke on background said the Navy's proposed plan to shrink the fleet is being driven primary from the Office of the Secretary of Defense, and that OMB is strongly behind the President's goal of 355 ship. “OMB strongly supports 355 [ships] and is working with the Navy on it,” the official said. “OSD seems to be the most opposed to it.” A Navy spokesman declined to comment on the contents of the memo, saying it was related to a budget still in development and was “pre-decisional.” The military has a policy of refusing to comment on budget matters before they've been submitted to congress. The fate of the cruisers has been a nearly annual fight on Capitol Hill, as the Navy has tried desperately to divest themselves of the troublesome class, though this year's proposed cancellation of six cruiser modernization plans did not make a stir on the Hill. The cruisers themselves are the largest surface combatants in the Navy's inventory but have become increasingly difficult to maintain. Cruisers have 26 more vertical launch system, or VLS, cells per hull than their Arleigh Burke Flight IIA destroyer counterparts, and 32 more than the Flight I Burkes. Cruisers act as the lead air defense ship in a carrier strike group but as they have aged, the fleet has managed everything from cracking hulls to aging pipes and mechanical systems. The ships' SPY-1 radars have also been difficult to maintain, as components age and need constant attention from technicians. Last year, the Navy proposed canceling the modernization of Bunker Hill, Mobile Bay, Antietam, Leyte Gulf, San Jacinto and Lake Champlain in 2021 and 2022. The new proposal would accelerate the decommissioning of the Monterey. Vella Gulf and Port Royal to 2022, which would cut between three and seven years off each of their planned lives. The plan would also advance the decommissioning of the Shiloh to 2024, three years earlier that previously planned. The service's past efforts to shed the cruisers to save money repeatedly drew the ire of former House Armed Services Committee sea power subcommittee Chairman Randy Forbes, R-Va., who didn't trust the Navy to keep the ships in service and therefore wrote clear language into several National Defense Authorization Act bills prohibiting the move. The Navy ultimately agreed to the so-called 2-4-6 plan in 2015, which allowed the service to lay up to two cruisers a year, for no more than four years and allow no more than six of the ships to undergo modernization at any one time. 'Making a Case' The 2030 deadline for 355 ships as mentioned in the OMB memo was first laid out earlier this month by acting Secretary of the Navy Thomas Modly in a speech at USNI's Defense Forum. “[Three hundred and fifty-five ships] is stated as national policy,” Modly told an audience on Dec. 5. “It was also the president's goal during the election. We have a goal of 355, we don't have a plan for 355. We need to have a plan, and if it's not 355, what's it going to be and what's it going to look like? “We ought to be lobbying for that and making a case for it and arguing in the halls of the Pentagon for a bigger share of the budget if that's what is required,” The speech was followed by the President's National Security Adviser Robert O'Brien at the Reagan National Defense Forum saying that Trump was serious when he committed to a 350-ship Navy. “When President Trump says a 350-ship Navy, he means a 350-ship Navy, and not decades from now,” O'Brien said. Bryan McGrath, a retired destroyer captain and analyst with the defense consultancy The Ferrybridge Group, said the plan to reduce the size of the fleet is a sign that the Defense Department isn't willing to put the resources required toward growing the fleet. “If what you are reporting is true, this is a sign of the tension between the grand desires for a much larger fleet and the modest resources being applied to the problem,” McGrath said. “There simply is no way to grow the fleet as it is currently architected while maintaining the current fleet at a high state of readiness with the given resources." McGrath said if 355 is still the goal, the Pentagon has to either dramatically restructure the fleet to switch out large surface combatants such as cruisers and destroyers with smaller, less expensive ships, or it has to change what's counted as a ship – both moves that have been signaled by the Navy in recent years. “This is why it's so hard to grow a Navy,” McGrath said. “You have to decide it's a national priority, you have to devote a lot of resources and you have to do it over a period of years. None of that has happened.” Dan Gouré , an analyst with the Arlington-based think tank The Lexington Institute and former Bush Administration Pentagon official, said trading existing force structure for unproven technologies such as unmanned ships that may pan out down the road is a classic Pentagon trap that rarely pans out. “It sends a bit of a chill up my spine to hear that the Navy may be considering cutting a bird in the hand for a theoretical eagle down the road,” Goure said. “That almost never works. I've been doing this long enough, 40 years of this, tell me when that's ever really worked.” https://www.defensenews.com/naval/2019/12/24/pentagon-proposes-big-cuts-to-us-navy-destroyer-construction-retiring-13-cruisers/
