It was meant to move with the forward battle area and shield the vehicles there. It weighed 63 tons, and in the end it was too heavy to keep pace with the vehicles it was built to cover.The program opened in February 1977 and ran in three phases: a 29-month competition between two contractors chosen from five, then a combined maturity and initial production phase, then follow-on production. The whole point was to put the gun in the field in about six and a half years instead of the usual twelve.What made it look sound was the hardware. Each contractor had to build from subsystems already working on other weapons, the Army held twelve firm requirements and let forty-three others be traded, and the [contract carried warranty cover](https://www.gao.gov/products/nsiad-86-89?ref=core-sector.ghost.io) well beyond what other major weapons had. | | THE TIMELINE | | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | Every row below comes from one document: the [General Accounting Office report](https://www.gao.gov/assets/nsiad-86-89.pdf?ref=core-sector.ghost.io) on the Sergeant York acquisition strategy, signed 30 May 1986 for the Senate Committee on Governmental Affairs. Column one counts the years from the day the program opened, and the report sets out both the original schedule and what actually happened against it.Read the two middle rows. Those are the production options. The report states that exercise of the options was tied to a designated calendar date rather than to a demonstration of technical performance. The dates arrived, so the units were ordered, and nobody had yet watched the gun work in a field. The third option was never exercised.CASE FILESergeant York, 1977-1985GAO/NSIAD-86-89Signed 30 May 1986YEARWHAT HAPPENEDWHENYear 0The program opens with five competing contractorsFeb 1977Year 4Ford Aerospace wins and signs three production optionsMay 1981Year 5The first option is exercised on its dateFY 1982Year 6The second option is exercised on its dateFY 1983Year 7Production is deferred until the tests are readSep 1984Year 8The first realistic test is read at lastAug 1985Year 10The year the gun would have reached units64 of 614 | | THE BREAK | | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Four things stood behind this, and the gun itself was the last of them.• **The options ran on the calendar.** Three production options were written to be exercised at one-year intervals, and exercise was tied to a designated calendar date rather than to a demonstration that the weapon worked. In February 1982 GAO asked for the decision to be deferred; the Army replied that the first option, for 50 units, had to be exercised by 31 May.• **The hard tests were booked for later.** Operation in a cold climate, durability under stress, transportability, and electromagnetic compatibility were all [put off until after](https://www.gao.gov/assets/c-masad-82-7.pdf?ref=core-sector.ghost.io) production had started.• **Very few people were allowed to look.** The Army held quarterly two-day design reviews at each contractor and read the reports they wrote. Oversight of early development sat with a handful of officials. Little reached the Office of the Secretary of Defense or Congress in those years.• **The law arrived two years late.** Public Law 98-94 of 24 September 1983 created an independent testing office and barred full production before its report. The decision to produce had already been taken. | ![The circled date](https://c1uhcpoz192mv2zskt.b-cdn.net/03e29afe-379f-42e5-9d61-65dac51a8912.jpg) | WHO PAID | | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | Nobody was hurt, because the gun never reached a unit. Sixty-four of the planned 614 had been delivered when the Secretary of Defense stopped the program on 27 August 1985\. Evaluators reported only a marginal improvement on the air defense the Army already had.The written record was better than the field record. In the six-month initial production test the gun met or exceeded 141 of 163 specifications; of the 22 it missed, Army evaluators marked seven as significant. The warranty covered those written specifications. It did not reach performance in an operational setting.GAO made three recommendations to the Secretary. All three are marked closed and not implemented, because there was no program left to apply them to. One vehicle survives: 63 tons of it went [650 miles on a truck](https://www.army.mil/article/45620/air%5Fdefense%5Fartillery%5Fartifacts%5Farrive%5Ffrom%5Ffort%5Fbliss?ref=core-sector.ghost.io) to Fort Sill in September 2010. | | THE PATTERN | | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | • **A date is not a result.** The option was exercised because the calendar said so. Nothing in it required the thing to have been shown to work first.• **Ask what the test was allowed to measure.** The warranty covered performance against a written specification under controlled conditions. It said nothing at all about the weapon in a field.• **Count the people allowed to look.** Early oversight sat with a few officials. The fewer the eyes, the longer optimism survives contact with the hardware.• **Speed counts only if it arrives.** The accelerated plan promised six and a half years. The projection at the end was ten, against twelve for the conventional programs it was built to beat.I sat through a review in 1996 where a program cleared its gate because the date had arrived, and the paper that would have stopped it was sealed in the next room.Gold answers it differently, since one bar is one weight and one assay in any year, so ask of any holding which of its numbers would survive a stranger running the test. |
