3m The smaller vessels were all approximately 90 meters long with a slightly
raked bow about three meters above the water line and with a transom stern
about a meter and a half above the water line,, Each had one funnel with a
smoke baffle immediately abaft the bridge,which was three meters high, and
two masts, one between the bridge and the funnel, and the other abaft the
deckhouse and much lower than the first. The hulls were painted gray. Each
was armed with a twin-mount forward with complete shielding, two completely
shielded twit=.-mpunts aft, and two sets of twt-mounted machine gums installed
aft, one port and one starboard, Only one radar antenna of unknown type was
observed. Two tubes,not over one meter long and placed one above the other,
were noted outboard on the port and starboard sides of the stern. During
their maneuvers, all the units mentioned above, two large vessels and six
light ships, never used visual signals; they :presumably gave their orders by
radio telephones As a matter of fact, all chinges incourse and changes i.r
speed were executed simultaneously with such precision that only rapid com-
munications and constant training made them possible. All of the ships were
smart looking, at least on the outside.
