Army to outfit all Double V-Hull Strykers with 30mm firepower
By: Jen Judson
WASHINGTON — The Army has decided to outfit all of its brigades equipped with Double V-Hull A1 Stryker Infantry Carrier Vehicles with 30mm guns following an evaluation of the vehicle equipped with the cannons in Europe, according to an Army official.
The service plans to open up a competition to integrate and field up-gunned DVHA1, the official told Defense News on background.
The Army Chief of Staff Gen. Mark Milley and the Army Requirements Oversight Council decided on March 20to equip future Stryker brigades with 30mm Medium Caliber Weapon System (MCWS) capability after reviewing lessons learned from the 2nd Cavalry Regiment in Europe, but also directed the Army to ensure that the new MCWS capability be applied to the more mobile, better protected DVH ICVVA1 that will be the basis for the future Stryker fleet, according to the official.
Based on an urgent operational need out of Europe, the Army was provided emergency funding from Congress in 2015 — a little over $300 million — to rapidly develop and field a Stryker with a 30mm cannon specifically for the 2nd Cavalry Regiment, which is permanently stationed in Germany. The funding covered development, eight prototypes and upgrades to 83 production vehicles, as well as spares.
The Army spent 18 months to put together its upgunned Stryker using off-the-shelf solutions, such as the remote turret, from Kongsberg in Norway, and the 30mm cannon from Orbital ATK and shipped those vehicles off to Europe for an evaluation that went on for the better part of a year.
The plan going forward is to execute a competition in two phases to select a 30x173mm-equipped MCWS integrated onto a Stryker DVH ICVVA1, the official said, which will lead to equipping the first brigade with a new capability in fiscal year 2022.
Army Contracting Command released a Request for Quote to begin the first phase of the Stryker MCWS program on April 9.
The recent request called for integration designs. The Army will award up to seven design integration study contracts for potential vendors to study integrating a MCWS onto a Stryker ICVVA1 platform.
The Army will supply both a Stryker platform and the XM813 30mm cannon to build production representative system samples, the official said.
The service will then circulate a draft request for proposal this fall to begin the second phase of the program, which will establish a full-and-open competition to award a production contract for a MCWS integrated onto an ICVVA1, which will be based on vendors' production representative system samples and proposals.
The MCWS will be part of a suite of lethality improvements for Stryker formations which include the Common Remote Operated Weapons Station-Javelin (CROWS-J) — that was also on the Stryker ICV Dragoon in Europe — and the Stryker Anti-Tank Guided Missile Vehicle (ATGM) engineering change proposal program.
The Army is also developing a host of other capabilities for the Stryker through the Army Futures Command Cross-Functional Team initiatives, according to the official.
Col. Glenn Dean, the Stryker program manager, told Defense News last fall that between early user testing in 2018 and subsequent fieldings, there had been an overall “very positive response” to the lethality and effectiveness of the Stryker ICVD.
“The cannon provides a tremendous standoff and additional maneuver space, and it is very effective against the threats they are concerned about in Europe,” he said.
But some feedback suggested that the physical layout of the vehicle could use some improvements, particularly when it came to situational awareness.
The turret for the cannon takes up a lot of roof and hatch space and also affects how equipment is stowed.
But the Army was already making modifications to the Dragoon based on feedback from the field, according to Dean.
It is unclear what the specific requirements might be for a more lethal Stryker, but one factor up for debate could be whether there is a need to reload and operate the turret under armor, which could change the physical nature of the vendors' designs.
Another issue to work out is what is necessary for a field-of-view inside the vehicle and how that might be achieved and who might control the cameras providing a view of the battlefield.
Soldiers in the Stryker ICVD noted a lot of dead zones where users couldn't see. The Army made improvements to the cameras used on the vehicles in Europe providing an overlapped field-of-view.

US Army to conduct shoot-off for future indirect fires protection
By: Jen Judson WASHINGTON — The U.S. Army plans to conduct a shoot-off to evaluate the best options for a future indirect fires protection capability to defend against rockets, artillery and mortars as well as cruise missile and drones, according to a report sent to Congress and obtained by Defense News. The shoot-off that will take place at White Sands Missile Range, New Mexico, is fashioned much in the same way the Army recently conducted its “sense-off” to choose a new air and missile defense radar that will replace the sensor in the Army's current Patriot system, Brig. Gen. Brian Gibson, who is in charge of the Army's air and missile defense modernization effort, told Defense News in a March 9 interview. The Army has been trying to formulate its enduring Indirect Fires Protection Capability Increment 2 (IFPC Inc 2) system for several years. It purchased two Iron Dome batteries, produced through a partnership between Rafael and Raytheon, to serve as an interim solution for cruise missile defense. The acquisition was congressionally mandated. Those batteries will be delivered by the end of the year, Gibson said. The enduring system will defeat subsonic cruise missiles with an objective requirement to defeat supersonic variants as well as group two and three UAS and RAM threats, according to the report. The Army's Sentinel A3 and future A4 version will serve as the radar for IFPC, and its command-and-control system will be the Integrated Air and Missile Defense Battle Command System, or IBCS, which is also the brains for the Army's future Integrated Air and Missile Defense system that will replace Patriot. The intention for IFPC is to protect critical fixed or semi-fixed assets and is intended to be a more mobile solution than one that would suffice at a forward operating base, Gibson described, and it will fill in gaps between tactical short-range air defense and strategic air and missile defense such as the Patriot and the Terminal High Altitude Area Defense System. The Army's analysis, according to the report, included looking at solutions both from the Israel Missile Defense Organization and from U.S. industry. It determined, when considering integration with IBCS and Sentinel as well as the possible schedule, that risks exist for both the U.S. and Israeli solutions. “Given the assessed risks with the potential enduring IFCP Inc 2 solutions, the Army requires additional performance data against IFPC Inc 2 threats,” the report stated. “The Army will use a competitive process consisting of two phases to reduce program risk, while considering cost and schedule parameters.” In the first phase, industry will participate in a shoot-off demonstration using proposed launcher and interceptor solutions integrated into IBCS and Sentinel. IBCS is entering a limited-user test in May after struggling through a previous limited-user test several years ago. The system has been delayed for various reasons and likely won't reach initial operational capability until the third quarter of fiscal 2022. Sentinel A4 is also not operational, so the shoot-off will use the less capable A3 variant. Following the shoot-off, the Army will evaluate proposals and data from the event, analyzing digital simulation data to make a “Best Value determination” to pick one vendor to move forward, according to the report. The shoot-off is planned for the third quarter of FY21. The Army aims to deliver initial capabilities by FY23. To make a determination on the way forward, the Army conducted analysis for an enduring IFPC solution in FY19 to include taking technical data from its Expanded Mission Area Missile program of candidate interceptors. The verification phase evaluated Raytheon's Low-Cost Active Seeker as well as its SkyHunter interceptor (the U.S. variant of Rafael's Tamir missile used in Iron Dome) and Lockheed Martin's Miniature Hit-to-Kill missile. All three of the interceptors were characterized as possible candidates for an IFPC interceptor. The Army originally planned to develop and field its own multimission launcher as part of the enduring IFPC solution but canceled that program in favor of finding a more technologically mature launcher. The service evaluated whitepapers for IFPC launchers and determined that those proposed required further development, prototyping and integration work to be used as a dedicated IFPC component, according to the report. The analysis also found the Iron Dome launcher and Tamir interceptor's performance “is highly reliant” on its own battle management system and multimission radar, and the report determined that “for Iron Dome's launcher and Tamir interceptors to be a viable option for Enduring IFPC Inc 2, the [battle management and weapons control] and [multimission radar] functions require transferring into the Army's IBCS.” And current data provided from the Israeli organization has not included component-level models such as the missile seeker, missile guidance and control, and missile fusing needed to verify that the launcher and missile would work with IBCS, the report stated. “The tightly coupled nature of Iron Dome components within the Iron Dome architecture and a lack of sufficient technical data requires further development, prototyping and integration in order to provide a potential Enduring IFPC Inc 2 capability,” the report noted. Through analysis, the service determined that the U.S.-based Expanded Mission Area Missile candidates met range and maneuverability requirements and would be able to tie into Sentinel A3 by FY23 and A4 by FY25. The Tamir interceptor's performance data proves its effectiveness when used within the Iron Dome system, but since data is lacking, it's uncertain how well it might perform when linked through IBCS to the Sentinel radar. Tamir, however, is likely to perform similarly to the LCAS missile, according to the report. While analysis shows that the interceptors are “likely” to meet enduring requirements, the shoot-off demonstration will “increase the Army's confidence in interceptor performance within the AIAMD architecture,” the report states. https://www.defensenews.com/land/2020/03/09/army-to-conduct-shoot-off-for-future-indirect-fires-protection-capability/
