Hi Ed,

It consists of the following changes:

    and holding circuit for the fire relay that will
    eliminate timing or sequence errors in the manual
    mode of fire.

(2) a missile heat monitor indicator for each launcher
    that will provide a visual indication of
    the missile heat status.

(3) an increase in time duration of the booster squib power
    application, that should insure the ignition of all 
    booster squibs.

LCI

(1) modification of the reject circuit

(2) improvement of the warhead monitoring circuit.

(3) monitoring of missile heat status at test stations

(4) rerouting of the missile away signal.

(5) rerouting of the cage-uncage circuit

(6) removal of glow coil power from test stations.


with kind regards from Germany, Michael Keller.
