S-3 Cable
The S-3 cable (figure 10-3) is an aluminum single-
conductor, buoyant cable terminated at both ends with
flexible copper conductors and terminals.
CL-1 and CL-3 Cables
The CL-1 and CL-3 cables (figure 10-4) consist of
one 450-foot length of hard-drawn, rope-stranded
aluminum conductor, core-sealed with an asphalt base
sealing compound, and jacketed with reinforced
synthetic rubber. Buoyancy is provided by shell-type
cylindrical plastic floats filled with foamed plastic. The
primary difference between the two cables is size. The
CL-1 is approximately 1 1/2 inches in diameter;
whereas, the CL-3 is approximately 2 1/2 inches in
diameter. Either the S-3 or the CL-1 is carried on board
MCM ships at all times. If the ship carries the S-3, it will
not carry the CL-1 and vice versa.
K-4 Electrode
The K-4 electrode (figure 10-5) consists of a
concentric stranded copper conductor cable covered
with cotton tape and seine braid. The K-4 electrode is
150 feet long and is terminated in flat lugs at both ends.
MAGNETIC SWEEP CONFIGURATIONS
The magnetic field produced by a ship consists of a
vertical component and a horizontal component. Each
sweep configuration is designed to exploit one or both
of those components. Therefore, the sweep
configuration to be used depends on which
component(s) must be exploited. The paragraphs below
illustrate the primary sweep configurations andidentify
the magnetic component(s) associated with each
configuration.
