US Army needs another year to pick protection system for Stryker
By: Jen Judson
WASHINGTON — The U.S. Army plans to take another year to pick an Active Protection System for its Stryker combat vehicle, according to the military deputy to the Army acquisition chief.
The service is already fielding the Rafael-made Trophy APS on its Abrams tank and has picked IMI's Iron Fist for the Bradley Fighting Vehicle — both as interim systems until the Army can develop an advanced future system — but it had to go back to square one when its attempt to outfit Stryker with Herndon, Virginia-based Artis LLC's Iron Curtain system failed.
The Army put out a request for possible systems to be qualified as an interim solution on the Stryker. Officials ultimately chose a Rafael and DRS team and a Rheinmetall and UBT team to participate in a live-fire rodeo last November to see if either system might work.
But while it was believed a decision would come soon after, Lt. Gen. Paul Ostrowski testified at an April 2 Senate Armed Services Airland Subcommittee hearing that it would take another year to make a decision.
“We have two companies that are in the process of competing for [APS on Stryker]. One is a venture between ... Rafael and DRS and the other is Rheinmetall and UBT, so we are in the process of going through that,” Ostrowski said. “It's going to take about a year, quite frankly, in order to put those systems on the vehicles, characterize them and make a determination as to whether or not to move forward with either one of the two vendors.”
Ostrowski added the service had asked each team to provide blueprints and to build their non-developmental APS systems to fit on Stryker. “They are in the process of doing that build,” he said.
“And once the build is put on the vehicle, it's then a matter of testing in order to ensure that it works,” Ostrowski said, which is not unlike the process the Army went through to characterize and qualify APS systems on both Abrams and Bradley.
Israeli company Rafael and DRS submitted its Trophy VPS — a lighter version of Trophy — for the rodeo. Germany-based Rheinmetall partnered with Unified Business Technologies, based in Michigan, and submitted its Active Defense System — now renamed StrikeShield.
During the rodeo, participants did not perform a full installation of their systems on the vehicle. Instead, they set up test rigs in front of Strykers or hung their system off a Stryker in the evaluation.
Following the rodeo, the idea was to select one, possibly two systems, to begin some sort of installation characterization on a platform deemed most appropriate for the APS system, Col. Glenn Dean, the Army's Stryker program manager who is also in charge of the interim APS effort, told Defense News in October 2018.
Meanwhile, Ostrowski said the Army bought 88 Iron Fist systems for Bradley in 2019 and planned to buy another 36 in the FY20 budget. The service is on a path to field four brigades of Abrams with Trophy by FY21.
The Army is also developing its own Modular Active Protection System, which is seen more like a digital integrated backbone that will be designed with an open-system architecture so that vendors can bring radars, optical sensors and hard- or soft-kill effectors and plug them in, according to Ostrowski.
The important thing is “to get a capability out there first. . . . Now it's just a matter of moving beyond that,” he said.

Sea-Air-Space Exposition 2019 Day One
By Mass Communication Specialist 2nd Class Brittney Kinsey, Defense Media Activity Public Affairs NATIONAL HARBOR, Md. (NNS) -- Sea service chiefs and civilian defense leadership discussed myriad opportunities and challenges commanders face while operating on land, sea and air during the first day of the 54th annual Sea-Air-Space Exposition (SAS), May 6, 2019. Derived from the Chief of Naval Operations' (CNO) Design for Maintaining Maritime Superiority 2.0 (Design 2.0), this year's exposition theme is “Sustainability, Agility, Superiority.” CNO Adm. John. M. Richardson, Commandant of the Marine Corps General Robert B. Neller, Commandant of the U.S. Coast Guard Adm. Karl Schultz and Administrator of the U.S. Maritime Administration retired Rear Adm. Mark H. Buzby each addressed during the sea service chiefs panel the specific obstacles their services contend with in the current maritime environment. Richardson explained that rapid changes in technology and maritime security requires a level of trust and confidence in leaders tasked with commanding maritime forces. “It's very important that our leaders are people of character and integrity so that when we put them in front of our Sailors to lead them, not only do they know their business in warfighting but also that we would be proud for our sons and daughters to follow them,” he said. “Whether at sea or near the sea, responding to any man-made or natural crisis, [they] are so much more than a maritime warrior, [they] are also diplomats and are securing our prosperity.” Richardson also stressed the importance of improving the logistical capabilities, stating that services will only maintain an upper hand in the maritime environment by becoming more agile. ‘'We have got to get capabilities into the hands of our soldiers, Sailors, airmen and Marines – more and faster,” he said. “It's important that as the pace quickens, as new technology enters the fray, as the security environment manifests itself in a really fast-changing world that we don't forget those fundamentals in terms of providing sustainable forces. ” During a panel on the Arctic, speakers explained why partnering with other services is also crucial to maintaining superiority, particularly in places like the Arctic Circle where there hasn't been a large naval presence. “When it comes to maritime readiness in the Arctic, we cannot and should not go alone,” said Rear Adm. John A. Okon, commander, Naval Meteorology and Oceanography Command. “Collaboration is key. Resources and access points are limited, so we must work with our maritime partners to be successful.” Richardson echoed Okon's comments during his keynote remarks at the Sea Services Luncheon. “The Arctic is a very dynamic situation,” he said. “There are seaways that are open that were not open before, continental shelves that are being exposed that weren't exposed before, so I think that merits a response from our maritime forces and there's tremendous value in partnering with our fellow services such as the Coast Guard.” Keeping the waters open for Indo-Pacific trade routes, which bolster global economic prosperity, also remains a top priority for the Navy. “A third of the world's trade flows through the South China Sea, 90% of the world's trade flows by the sea, tens of trillions of U.S. dollars flow through that body of water,” said Richardson. “It's extremely important that those lines of communication and sea lanes remain open, and that's why the United States Navy is there and that's why we're going to stay there.” Other scheduled keynote speakers and panelists include Secretary of the Navy Richard V. Spencer, Undersecretary of the Navy Thomas Modly, Assistant Secretary of the Navy for Research, Development and Acquisition James “Hondo” Geurts and Master Chief Petty Officer of the Navy Russell Smith. Founded in 1965 and the largest maritime exposition in the United States, SAS brings together the U.S. defense industrial base, private sector U.S. companies and key military decision makers for an annual event to share the most current policies, programs, information and technology relevant to maritime service. SAS takes place May 6-8 and will include speaker and professional development sessions and dynamic maritime and defense exhibits on the latest technology and military equipment. https://www.navy.mil/submit/display.asp?story_id=109502
