28. J-9, 20 Dec 60, Response Mode 4, Flight Phase 2: No Stage-Ilignition due to failure
of gas generator to start.
29. J-10, 20 Jan 61, Response Mode 4, Flight Phase 2: No- Stage-II operation due to
erroneous signal that appeared at umbilical disconnect. Impact some 420 miles
downrange.
32. J-12, 3 Mar 61, Response Mode 4, Flight Phase 2: Stage-II terminated prematurely
after 54-second burn, apparently due to failure of pump drive assembly. Impact
was 730 miles downrange.
34. J-15, 31 Mar 61, Response Mode 4, Flight Phase 1: Booster shut down prematurely
at 74 seconds. Missile subsequently tumbled and broke up.
37. M-1, 24 Jun 61, Response Mode 4T, Flight Phase 2: Stage II engine shut down
prematurely after 12 seconds of operation due to loss of Stage II hydraulic power.
Loss of hydraulic power occurred during Stage I flight, so failure led to loss of
control of sustainer and vernier actuators, producing excessive missile motion and
tumbling.
42. M-3, 7 Sep 61, Response Mode 5, Flight Phase 2: A transient in guidance computer
at 218.35 seconds (SECO at 297.7 seconds) caused impact 20 miles short and 2.8
miles left of target.
45. M-4, 6 Oct 61, Response Mode 5, Flight Phase 2: A one-bit error in the W velocity
accumulation caused impact 86 miles short and 14 miles right of target.
50. M-6, 15 Dec 61, Response Mode 4, Flight Phase 2: Start signal for Stage II was not
generated. Stage II did not ignite.
51. I, 20 Jan 62, Response Mode 4, Flight Phase 2: Missile self-destructed, apparently
after Stage 2 failed to ignite. A backup automatic fuel-cutoff signal was sent at
248 Seconds. •
53. I, 23 Feb 62, Response Mode 4, Flight Phase 2: Missile sell-destructed, apparently
after Stage 2 failed to ignite. A backup automatic fuel cutoff signal was sent at 240
Seconds.
56. N-1, 7 Jun 62, Response Mode 4, Flight Phase 2: Sustainer engine performance was
subnormal due to reduced oxidizer flow through the gas generator. RSO
terminated flight after a prolonged sustainer bum. Impact only 1100 miles
downrange.
58. N-4, 25 July 62, Response Mode 4, Flight Phase 2: After about 60 seconds of Stage
II bum, a fuel leak between the thrust chamber valve and the injector resulted ·in a
