Track'ng Radar Simulator
Marconi Radar Systems are
supplying a 350 000 Pound Sea Dart
radar simulator for the Royal Navy's
School of Tactics. Navigation and
Action Information Organisation.
H.M.S Dryad.
The equipment will take its place in
the part of the trainer simulating the
operations room and weapon
control systems of the new Type 12
destroyers, which are to carry the
Sea Dart (GWS 30) surface-to-air
guided missile system.
The simulator will be used to train
command and operations room
teams of the future fleet, and it will
provide a completely realistic sea
exercise at only a fraction of the cost
of actual sea training. Tests for the
operators will be programmable and
Dryad instructors will be able to
assess their students' performance

Fast Training Boats
H.M.S. Scimitar is the lead ship in a
new class of three fast training boats
for the R.N. The other two are H.M.S.
Cutlass and H.M.S. Sabre. These 100-
ton training craft are of wooden construction
with aluminium alloy
superstructures. They have an
overall length of 100 feet and a beam
of 26 feet. Manned by two officers
and ten sailors, the vessels have a
CODOG propulsion system — gas
turbine main engines, and a diesel you've ever left a bottle of water to
auxiliary engine — providing a top stand outside. The green scum
speed of approximately 40 knots which forms on the inside surfaces
of the bottle consists of algae. In
Small Fleet Auxiliary dried-out form, these tiny little
This new Royal Fleet auxiliary
Graan Rovar, is designed to replenish
Royal Navy ships with fuel, fresh
water, dry cargo and refrigerated
stores under all weather conditions.
She is 461 feet long, has a beam of
63 feet, a deadweight tonnage of
about 7.000 tons and is manned by
42 officers and men. The ship has a
helicopter landing platform, served
by a stores lift, for transfer of
supplies by air.

Algae and Cakes
Cakes baked from a flour derived
from algae may. in the years to
come, make an important contribution
to the campaign to overcome
the protein shortage in the diet of
millions throughout the world.
Algae are small vegetable
organisms existing in vast quantities
in water — as you will know if
plants float around the atmosphere
in a state of suspended animation.
Wherever there is water, they come
to life again and quickly multiply.
Most algae have a high protein
content. Since a considerable
proportion of the world's population
suffers from protein deficiency, any
means to place extra protein at the
disposal of undernourished people
at low cost is most welcome indeed.
This explains why an experimental
farm in Mexico, run by F.A.O.. the
United Nations' Food and Agriculture
Organisation, has been
testing ways to grow algae for
human consumption.
After "harvesting". the algae are
pulverised, sugar is added and a new
type of flour is obtained. The testers
have been using this flour to bake
cakes: they claim that in addition to
being highly nutritious, their cakes
are actually quite tasty.
UNITED STATES OF
AMERICA
Hydrofoil Gunboat Prototypes
The U.S. Navy has awarded to
Boeing a sole-source contract for the
construction of two 170-ton PHM
hydrofoil gunboat prototypes,
equipped with surface-to-surface
versions of the McDonnell Douglas
Harpoon missile. The U S.N. is
reported to be anxious to obtain the
operational version of the Boeing
hydrofoil (based on the Boeing 60-
ton experimental Tucumcari gunboat)
as soon as possible to counter
the U.S.S.R.'s SS-N-2 Styx cruise
missile system, which is carried by
Soviet patrol boats as well as larger
vessels and has a range of about
25nm. If the evaluation trials are
