Government watchdog warns of cost and technical risk for next-gen combat vehicle effort

By:

WASHINGTON — The Government Accountability Office is warning the Army its approach to cost estimates and technical development for its Optionally Manned Fighting Vehicle program is risky and should be amended, according to an August 6 report.

The Army has already struggled to get the OMFV program, intended to replace the Bradley Fighting Vehicle, off the ground, canceling its previous solicitation to compete after receiving just one bid from General Dynamics Land Systems last fall.

And GAO, in its report, is concerned that the service's newest attempt to get after delivering an OMFV comes with risk because the program documentation “does not clearly communicate the uncertainty associated with projected costs” and limits the program's “ability to gather the knowledge to effectively mitigate risk associated with system design maturity.”

For one, the Army has come up with a singular cost estimate for the life-cycle of the program rather than a range of potential costs that takes uncertainty into account, according to the report.

The OMFV program cost estimate, the report notes, is roughly $46 billion in fiscal 2019 dollars.

“Our past work has determined that a point estimate alone is insufficient for managers to make informed decisions about the cost of a program,” the GAO writes. “For informed decisions, the cost estimate must reflect a degree of uncertainty, typically achieved through an uncertainty analysis, so that level of confidence can be given about the estimate.”

For example, the OMFV program will be optionally manned, “which adds complexity and unknowns to the design as no vehicle like this currently exists in the Army's ground vehicle fleet,” the GAO said. “But the uncertainty surrounding this complex design is not reflected in the point estimate.”

And because of this “decision makers are left making choices without a clear understanding of the impact on costs and may not be able to accurately budget for the program,” the report states.

The constrained development schedule for OMFV is also a cause for concern as it inevitably drives risk into the program. GAO notes the Army had laid out, in its previous solicitation, a plan to design and demonstrate an OMFV prototype in three years and three months, but has since spread the schedule out a bit more with the relaunch of the program and now plans to complete system development and prototype demonstration in “close to” five years.

The new solicitation also lays out a five-phase effort that will allow the Army to reassess the process at certain checkpoints throughout development, according to the report. The GAO also found promise in the Army's plan to use a modular open systems architecture to incorporate incremental upgrades.

In the Army's previous plan for OMFV it also planned to use a mix of existing and new technologies but, the GAO report states, the program did not include plans to complete an independent technology readiness assessment until it was approaching a production decision.

According to the Office of the Under Secretary for Defense for Acquisition and Sustainment, in a report to Congress, “the least mature technology for OMFV had only been demonstrated at the component level in a laboratory environment,” the report notes, adding that the level of technology maturity would require “significant” additional development before it could be added to a weapon system.

“The Army is maturing, or has plans to mature, individual technologies to a level lower than the threshold recommended by leading practices before beginning system development,” the report says. “This creates a danger of limited insight into key technology risks.”

Critical technologies, GAO states, should be demonstrated in “an operational or realistic environment — not simply in a relevant environment — prior to their incorporation into a system design to ensure that they work as intended for the end-user.”

The GAO adds, based on past experience, that without proving out technology at that level, the Army risks the possibility that new capabilities won't work as planned and will require further maturation, which results in schedule slips and rising costs.

In the previous competition, OMFV didn't hold a systems engineering design review before beginning system development and the Army canceled the solicitation “in part due to the conclusion that contractors could not complete a system design that met requirements within the given schedule,” the report notes, which “illustrates the risk of beginning system development without conducting a systems engineering design review.”

Program officials told the GAO that the program office and requirements developers “may have misjudged the ability of contractors to integrate the desired technology within the given schedule.”

The GAO recommends the Army secretary direct the OMFV program office to include a range of cost estimates to support a range of possible outcomes as well as conduct systems engineering reviews at key decision points.

The report also lays out similar findings on the Mobile Protected Firepower program, which is heading into competitive prototype testing this summer. General Dynamics Land Systems and BAE Systems are competing to build the new light tank for Army infantry.

The GAO recommended the Army should ensure the MPF program also include a range of cost estimates that account for uncertainty.

    U.S. Air Force will fund research into tech that enables eVTOL aircraft

    The U.S. Air Force is looking to fund research into “deep tech” for eVTOL aircraft through its next round of Small Business Technology Transfer (STTR) contract awards. By Elan Head An award-winning journalist, Elan is also a commercial helicopter pilot and an FAA Gold Seal flight instructor with helicopter and instrument ratings. Follow her on Twitter @elanhead View more posts NEWS U.S. Air Force will fund research into tech that enables eVTOL aircraft Monday July 6, 2020 The U.S. Air Force is looking to fund research into “deep tech” for eVTOL aircraft through its next round of Small Business Technology Transfer (STTR) contract awards. The focus on technology research is one more aspect of Agility Prime, the Air Force's effort to accelerate development of the commercial eVTOL industry with the goal of establishing U.S. dominance in this emerging field. Speaking during an Agility Prime webinar on July 1, Dr. Will Roper, Assistant Secretary of the Air Force for Acquisition, Technology and Logistics, suggested that the Air Force could help fill a funding gap left by Silicon Valley investors who have increasingly prioritized software enterprises that promise faster returns. “We want to take risk by investing in deep tech,” he said. “For programs like Agility Prime that are going to be tackling a lot of really tough challenges — from power to flight safety to logistics — there's a lot of really cutting-edge tech that has to be created, has to be matured and developed, if we're ultimately going to bring this market to bear in the U.S. first. Well, STTR is a great place to start tackling the hard challenges now.” STTR is a federal government program created to help commercialize compelling technology from across the U.S. research community. Like the Small Business Innovation Research (SBIR) program, it focuses on three phases — concept development, prototype development and commercialization — with various funding amounts available for different phases. Unlike SBIR, however, STTR requires that participating small businesses partner with an eligible nonprofit research institution. According to Roper, the Air Force devotes around $700 million per year to SBIR and another $200 million to STTR projects — not all of which will yield results. “We don't expect every company in STTR to succeed, just like we don't in SBIR,” he said. “This is an investment portfolio, so we're looking for return across the whole portfolio, not [on] a company-by-company basis. But we should start planting the long-lead seeds now, because if we don't, they're not going to bloom in time for us to harvest in a way that will benefit programs like Agility Prime.” The Air Force's next STTR Open Topic solicitation will include an Agility Prime focus area, intended to survey a large scope of technologies including autonomy, advanced aircraft materials and manufacturing, novel acoustics techniques, and sense-and-avoid systems, to name a few. The Air Force expects to award an estimated $10 million worth of phase one contracts for values up to $150,000 within 90 days. According to Jared Evans, a partner in AFVentures who also spoke during the webinar, phase two contracts are expected to have an initial value of $750,000, with the most promising projects then eligible for a “strategic fund increase” up to $30 million. “Ultimately, our end goal here is . . . transitioning to a full program of record,” he explained. “There's no STTR funding for that, but there's also no limit on government input or private investment.” In advance of the solicitation, the Air Force innovation division AFWERX will be hosting a virtual TeamUp event with the Air Force Research Laboratory (AFRL) on July 15 and 16. The first day of the event will be open to the public and will include an overview of STTR funding opportunities, plus a virtual trade show. The second day will be restricted to Agility Prime ecosystem members who have chosen to register for a virtual booth, with the aim of facilitating connections that could lead to collaborative STTR proposals. Registration for the event is available here. “TeamUp events like this one will provide opportunities for multiple stakeholders to come together and compete with speed,” stated AFWERX director and Agility Prime team lead Col. Nathan Diller in a press release announcing the event. “Just like AFWERX and AFRL are teaming up to bring cutting-edge commercial technology together with world-class research, we are encouraging entrepreneurs and researchers from around the country to ‘TeamUp' in a way that strengthens our national security and prosperity.” https://evtol.com/news/air-force-agility-prime-sttr/
