MARTIN RB-57E “PATRICIA LYNN”
Two B-57Es were modified for special reconnaissance missions
and sent to Southeast Asia beginning in May 1963 -- becoming
the first jet aircraft assigned in Vietnam. The modifications,
done by General Dynamics rather than Martin, included altering
the nose to house a 36-inch forward oblique camera and a
panoramic camera. The lengthened nose gave the aircraft --
redesignated RB-57E "Patricia Lynn" -- a distinctive
appearance. These aircraft were also fitted with infrared
sensing equipment and began combat operations flying out of
Tan Son Nhut Air Base, South Vietnam.
In December 1964 two more B-57Es were modified to RB-57E
specifications and sent to Vietnam. A fifth aircraft was
received in November 1965. These five aircraft formed
Detachment 1 of the 460th Tactical Reconnaissance Wing
(earlier 6250th Combat Support Group and earlier still 33rd
Tactical Group).
The United States began Operation Steel Tiger over the
Panhandle and the DMZ on April
3, 1965, to locate and destroy enemy forces and
materiel being moved southward at night into South Vietnam. On
a typical mission, the RB-57E was accompanied by B-57B
"Night Intruder" bombers and C-130 flare ships.
After a strike, the "Patricia Lynn" aircraft would
complete a bomb damage assessment reconnaissance run over the
previous attacked target area.
Two RB-57Es were lost in combat operations. The first (S/N
55-4243) was lost as a result of a fuselage fire caused by
small arms while on a low level reconnaissance mission. The
crew ejected safely when near Tan Son Nhut Air Base. The
second aircraft (S/N 55-4264) was lost on Oct. 15, 1968, after
an engine fire started by ground fire forced the crew to
eject.
One more RB-57E was converted as a replacement for the combat
losses. This aircraft had a Terrain Following Radar designed
to allow the aircraft to fly at a constant altitude, which
would, in theory, produce better reconnaissance photos.
Unfortunately, the aircraft flew so low (500-1000 feet) that
the infrared film was used up before the entire assessment
area could be photographed.
The RB-57E "Patricia Lynn" aircraft continued
flying missions into the late 1960s including Barrel
Roll strikes in 1969. The aircraft were withdrawn
from combat operations in mid-1971.
