ome Kiowas’ Block 1 Air-to-Air Stinger
(ATAS) interface electronics assemblies (IEA)
were installed before it was decided to add an
electromagnetic interference (EMI) filter to the J1
connector.
Without the
EMI filter, static
could affect the
Kiowa's commo.
MWO 9-1440-
431-50-1 (Oct
01) authorized
the filter.
It's simple to check if the filter has been
installed. Disconnect the J1 connector at the IEA.
Look at the area at the base of the pins. If the fil-
ter's been installed, you'll see "EESeal". Not
there? Contact your AMCOM logistics assistance
rep. He will arrange for the MWO to be done. The
AMCOM POC for the MWO is Cynthia Walker.
Contact her at (256) 876-3515/DSN 746-3515 or

AN/ALQ-144A…
C
rewmen, your AN/ALQ-144A(V)1/3 countermeasure set performs an important
job in jamming heat-seeking missiles. But now a recent upgrade accomplished by
MWO 11-5865-200-30-1 (1 Mar 01) will enhance its performance even more.
CECOM has an upgraded A9 circuit card, NSN 5998-01-464-2151, that’ll keep
your set humming.
To determine if your countermeasure set needs an upgrade, check the A9 card for
a red strip on the U4 chip and a red dot on the S1 thumb wheel switch.
If U4 is missing a width-
wise red strip or s1 is
missing a red dot on the
side, contact cecom’s Cliff
Vermont at DSN 992-2472,
(732) 532-2472 or e-mail
cliff.vermont@
mail1.monmouth.army.mil
for upgrade details.
He’ll help you
accomplish the a9 circuit
card upgrade process.
