DOT&E FY 2020 ANNUAL REPORT

https://www.dote.osd.mil/Publications/A ... al-Report/
  • Infantry Squad Vehicle (ISV)
    Assessment
    • Based on performance demonstrated in STP2 and DT, the ISV provides enhanced off-road mobility capability and enables infantry units to be less predictable in their movement necessary to accomplish airborne; air assault; offensive; and engagement, security cooperation, and deterrence (ESD) missions. The ISV expands a light infantry unit’s area of operations. Squads equipped with ISVs accomplished nine movement tasks consisting of 50 miles each during the STP2. All ISVs were capable of carrying a nine-soldier infantry squad with their personal weapons and equipment during movement.
    • The ISV has not demonstrated the capability to carry the required mission equipment, supplies, and water for a unit to sustain itself to cover a range of 300 miles within a 72-hour period. The lack of internal space to carry soldiers with their rucksacks in seats, mission-essential equipment, and sustainment loads may create a logistics and operational burden. This limits the type and duration of missions for which an ISV may be effective. Units operating for long duration will need to conduct mission planning, cross-level equipment across the unit, or may require additional ISVs to sustain operations.
    • The Army did not conduct airborne, air assault, offense, defense, and ESD missions during the STP2. All ISVs have the capability for internal transport by C-17 and CH-47F in support of airborne missions. Based on DT, all ISVs meet the weight and dimension requirements to fit inside a C-17 and CH-47F, and meet the 5,000-pound weight limit to permit sling loading with CH-47F and UH-60 helicopters. The Army plans to test and evaluate the ability of an ISV-equipped unit to accomplish these missions during IOT&E.
    • Units equipped with ISVs lack reliable communication capability using hand-held radios and manpack radios over the distances of 62 to 300 miles required to accomplish missions. The ISV does not have a requirement for a mounted communication capability. During the STP2, each squad depended on their squad radios while employing ISVs. Communication between the squad leader, soldiers, and the platoon leader was intermittent and not reliable.
    • General Motors Defense ISV demonstrated the highest reliability amongst the three vendors in DT. The General Motors Defense ISV demonstrated a 585 mean miles between operational mission failure (MMBOMF) versus the user requirement of 1,200 MMBOMF.
    • All vendors’ ISVs are cramped and soldiers cannot reach, stow, and secure equipment as needed, degrading and slowing mission operations. During the STP2, soldiers on all ISVs could not readily access items in their rucksacks without stopping the movement, dismounting, and removing their rucksacks from the vehicle.
    • The ISV does not have an underbody and ballistic survivability requirement. The ISV-equipped unit will be susceptible to enemy threats and actions. All ISVs have some design features to reduce a unit’s vulnerability to enemy detection such as speed, and a small, low profile design that minimize their visual detectability. In order for the ISV-equipped unit to avoid threats and traverse terrain that is covered and concealed, the ISV will give up some of its inherent speed advantage.

Infantry Squad Vehicle is a cramped ride, but US Army says it meets requirements
The U.S. Army’s new Infantry Squad Vehicle is a cramped ride and offers limited protection from certain threats, according to a recent report from the Pentagon’s chief weapons tester, but it still meets the service’s requirements in tests and evaluations, the product lead told Defense News.

The ISV “key requirements are being met and we are increasing soldier operational readiness by providing an operationally relevant vehicle that can transport small tactical units to a dismount point faster and in better physical and mental condition for the fight,” said Steven Herrick, the Army’s product lead for ground mobility vehicles within the Program Executive Office Combat Support and Combat Service Support.
But the Pentagon also noted the ISV “has not demonstrated the capability to carry the required mission equipment, supplies and water for a unit to sustain itself to cover a range of 300 miles within a 72-hour period.”

The Army, however, has assessed the ISV requirement and solution set is in alignment, Herrick said. The DOT&E report, he said, “indicates a desire to include more equipment than a standard nine-soldier squad would carry on a 72-hour mission.”

This lack of space, the report stated, “may create a logistics and operational burden” and might limit the type of missions and duration for ISVs.



The soldiers that participated in the touch point evaluating the vehicles were asked to bring their Advanced Combat Helmet and Improved Outer Tactical Vest with plates; individual weapon; night vision devices; and ruck with three days’ worth of supplies, Herrick said.

“All vendors’ ISVs are cramped and soldiers cannot reach, stow, and secure equipment as needed, degrading and slowing mission operations,” the report explained. During tests “soldiers on all ISVs could not readily access items in their rucksacks without stopping the movement, dismounting, and removing their rucksacks from the vehicle.”

The soldier touch point took into account soldier comfort, visibility and ability to execute the mission, Herrick said. This was all factored into the Army’s decision to choose GM Defense’s vehicle.

“Additionally, no current or planned combat or tactical vehicle allows access to rucksacks while moving to support operator safety,” Herrick noted. “Crew spaces on the ISV are designed to allow mission performance of specific duty tasks.”



Units also lacked reliable communication capability, according to the report, using hand-held or manpack radios between 62 and 300 miles. The ISV does not have a mounted radio requirement. “Communication between the squad leader, soldiers, and the platoon leader was intermittent and not reliable,” the report found.

Because of the concept of the ISV providing an effective aid to insert soldiers into combat operations, the requirements support just what the soldier carries, so there is no mounted requirement yet, Herrick said. That requirement could be added as a growth capability later.

The DOT&E report also noted that the ISV doesn’t have an underbody and ballistic survivability requirement, which could mean the unit would be susceptible to certain threats, but the ISV’s speed as well as its small, low profile might help deal with those issues. Adding protection to the vehicle would sacrifice the speed the squad needs to rapidly inject itself into operations.

Overall, GM Defense’s vehicle had the highest reliability among the three vendors, demonstrating 585 mean miles between operational mission failures. The Army’s user requirement is 1,200 mean miles for that situation.

Herrick noted that reliability and maintainability testing was not scheduled or conducted by Army Test and Evaluation Command or the program office, so the calculations used in the DOT&E report were “not supported by traditional [reliability and maintainability] RAM elements, such as scoring conferences and time for the vendor to implement changes.”

The mileage accumulated and referenced in the report was “not meant to evaluate RAM by the Army, but rather to provide the program office and contractor an initial insight on the capability of the system over 500 miles,” Herrick added. The vehicle’s RAM testing is scheduled to begin this month, he added..

The service wasn’t able to evaluate every aspect of the vehicle before moving into production, but it plans to test the vehicle’s ability to be carried by a Chinook during its initial operational test and evaluation this year.

US Army begins ‘light tank' soldier assessment without BAE Systems' prototype
The army kicked off its Mobile Protected Firepower (MPF) soldier vehicle assessment (SVA) on 4 January and it is anticipated to continue through to June, Ashley John, director for public and congressional affairs for the Program Executive Office for Ground Combat Systems, told Janes on 27 January. Under the larger programme, both BAE Systems and GDLS are under contract to deliver 12 MPF prototypes to the army and soldiers are slated to test out four vehicles of each variant. However, this testing phase began with vehicles from only one company – GDLS.

“We have received 12 prototypes in total, and four ballistic hull and turrets,” John said. “We will continue to receive the remaining prototypes throughout fiscal year 2021.”

Although John did not disclose which company produced the delivered prototypes, a GDLS spokesperson confirmed that the company delivered its 12th and final prototype to the army at the end of December 2020. GDLS’s delivery completion means BAE Systems has delivered only two ballistic hulls to the service.
