submerine to be bearing 2a4°T, distance 31 miles
from the reference poirt.
An estimated course of
045°r, speed 7 for the submarine was reported.
A
plane and FARNINS (DDR 877) proceeded to scene
and FERKINS made contact at 1700 Mike.
Both ships
held contact, destite temporary lapses, until
1951 Mike when contact was lost and not regained.
The search was continued until 0700 Mike, 21 February, by RABY, PERKINS, and one PM with negative
results.

Visibility was sood and water clear, but no visual
sighting of periscope or submerged submarine occurred
at any time.
(3)
RABY challenged by sonar without reply.
Based on sound characteristics of: (a) good echoes;
(b) characteristic recorder traces; (c) fairly con-
sistent doppler effect; (d) propeller noise; and
(e) loss of contact at ranges under 400 to 500 yards;
it is considered thet the target was a submarine at
deep submergence.
(4)
A plot of track showed various courses and low speeds
with general movement about one kmot towards the
northwest.
(5) The evaluation of this contact is "PROBABLE."
