Co, Solana Beach Ca is intended for use by crewmembers of B-52
and B-47 aircraft engaged in Airborne Alert missions and all
crewmembers engaged in the operation of helicopter aircraft.
Assigned Feb 28, 1961.
Note:
Bill Jack Helmet Division was sold to CAL-MIL Plastics in
1965 and the model numbers were retained.
The
Helmet is constructed of rigid fiberglass reinforced
plastic shell, a suspension system consisting of a full
foamrubber liner with resesses for earphones. The
foamrubber liner is covered with a rayon cloth liner. An
adjustable nylon chin strap completes the helmet
assembly. Chin start may be equipped with cup and
microphone holder.
Earphone and cable of the H-149/AIC headset is used for
communications making the helmet compatable with
AN/AIC-10 intercom system installed in the aircraft.
The helmet (pictured at left) can use either the MBU-5/P
or MBU-3/P Oxygen masks. The Nuclear flash blindness
goggle (M-1944 with gold lens) is attached as per the
picture.
An optional sun visor can be attached to the three
snaps, but according to the assignment sheet, this was
not a standard item (specifically listed as NOT used).
Issued in three sizes: Small, Medium and Large. The
inner foamrubber liner came in six sizes to allow custom
sizing. |
