a. Organization of Gliderborne Troops
Gliderborne troops constitute one of the two German Air Force components
operating under the Fliegerkorps XI. They are known
as Sturmtruppen (assault troops) and are organized into
a Sturmregiment. Although technically airlanding units, they must
not be confused with the airlanding Army troops, which are infantry units.
Troops transported by gliders function in close conjunction with
parachute troops and the Army airlanding detachments. In the general
pattern of operations, they precede the parachute troops and, by their
noiseless approach, utilize to the fullest the element of surprise. Their
mission is to neutralize antiaircraft and other defenses, and to disrupt
all communication systems. They thus prepare the way for the parachutists
who seize landing ground for the transports bearing the airlanding Army troops.
The assault regiment has a full strength of almost 2,000 men and is
organized into 4 battalions having a total of 14 companies. Each of
the first 3 battalions is broken down into a headquarters and signal
unit, a heavy weapons company, and 3 rifle companies of 120 men
each. A rifle company consists of 4 platoons, plus a headquarters
and signal unit. Each platoon is divided into 3 sections
of 10 men each. The fourth battalion includes a headquarters
unit, a signal section, and 2 companies, infantry-gun and antitank.
The DFS-230 gliders, in which the assault troops are normally carried, are
organized into a special air transport unit known as
the Luftlandung Geschwader, the smallest operational unit of which
is a Kette of 3 gliders. Each glider carries a complement of 10 men, which
is a section of a platoon. Three flights or Ketten make
up a Gruppe. The Geschwader is, therefore, composed
of 4 Gruppen with a total of 192 gliders and can transport
the entire Sturmregiment of approximately 2,000 men.
b. Training
Glider pilots generally have had previous experience in civilian glider
flying, although this does not qualify them for handling a freight-carrying
glider. A 6 weeks' course in gliding is given in special training schools, particular
stress being placed on spot landings. Training on large gliders is conducted
within the glider unit itself. The troops carried by a glider are graduate
parachutists; however, they do not normally wear parachutes in gliderborne
operations. It is debatable that they parachuted from gliders over Crete as has
been reported.
Training gliders are believed to fall within three classes according to
wing span. The "A" class glider has a wing of high aspect ratio with 55- to 60-foot
span and usually a very short nose. It is possible that some gliders in
this class may be high-performance sailplanes. Gliders in the "B" or
intermediary class, having a span of 35 to 50 feet, are probably the
most widely used. The "C" class gliders, with a span of 33 to 35 feet, are
believed to be used for primary training.
c. Types of Gliders
Up to the present time the DFS-230 mentioned above is the only troop-carrying
glider that has been identified as carrying assault troops during operations. The
Gotha-242 (see following sketch), which has often been referred to as one of the
principal troop transport gliders, is used almost entirely for carrying
freight. This high-wing, dual-controlled glider is reported, however, to
be capable of carrying 21 fully equipped men in addition to 2 pilots.

GERMAN GLIDER -- GOTHA-242 |
The Merseburg, which has been mentioned as a tank-carrying glider, has been
estimated to accommodate 40 to 50 men, while the Goliath is veritably the giant
glider that its name implies. This twin-fuselage glider is believed to have a
wing span of 270 feet and a wing area of 7,500 square feet, and to
carry 17 to 20 tons or 140 fully equipped men, 70 in each fuselage. These
gliders are in a more or less experimental stage and are therefore not
considered for the purpose of this discussion as a part of
the Geschwader organization.
The DFS-230 used in the Cretan campaign is a high-wing monoplane with
a wing span of 71 feet 5 inches and a length of approximately 36 feet. It has
fabric-covered wings and a fuselage of steel tubular construction. The wheels
can be jettisoned after the take-off, and a landing is effected on a central skid. The
empty weight of this glider, fixed equipment included, is approximately 2,200 pounds, and
the (tare) fully loaded weight 4,600 pounds. Weight varies according to the
assignment involved; a useful load is probably about 2,400 pounds.
This glider will carry nine fully equipped men and one pilot. Seats are
arranged in a single line on a boom running along the center of the fuselage, six
facing forward and four backward. The rear seats are detachable in case more
space is needed for freight. A 24-volt storage battery installed in the nose of
the glider furnishes power for navigation, cabin, and landing lights. A fixed
light machine gun (LMG-34) is believed to be attached externally to the
starboard side of the fuselage and fired by the man in the seat behind the
pilot. Instruments on the panel of the DFS- 230 include altimeter, compass, and
airspeed, rate-of-climb, and turn-and-bank indicators.
The DFS-230 is ordinarily towed by a Ju-52 aircraft, which normally flies
empty. Towing planes usually fly in a Kette; but when two or three gliders
are towed, each is attached directly to the tug in V-formation. The glider is
towed by means of a rope or a steel cable attached to a hook in the tail of the
aircraft and fitted with a quick-release mechanism. The length of the towing line
depends on the airfield space available; the longer the rope the easier the
handling. A multiple tug arrangement probably would be necessary to tow a
glider the size of the Goliath or the Merseburg. Three or four Me-110's or
three Ju-52's might give a reasonable performance, although this would be a
difficult operation.
d. Glider Operations
Gliders do not require large landing areas, runways being desirable but
not essential. The landing run of a DFS-230 is said to have been shortened
by wrapping barbed wire around the skids. Flaps are used to steepen the
angle of the glide. In case of Me-110's being used as tugs, rocket-assisted
take-off may be necessary when using airdromes with runways less than 2,000 feet.
The range of operations of a glider is obviously dependent on the range
of the towing aircraft. The total range for the Ju-52 with 530 gallons of fuel in
still-air conditions when towing one DFS-230 is about 780 miles, or 600 miles
for three gliders. This will allow an approximate radius of action of 250 miles. With
extra fuel a Ju-52 is reported to be able to tow a DFS-230 more than 1,000 miles.
The distances which gliders can cover after the release vary according
to altitude of release, direction and force of wind relative to line of
flight, navigation errors, and evasive action. The gliding distance for
the DFS-230 has been calculated in the ratio of 1 to 16 in still
air, i.e. for every foot of descent, the glider theoretically
covers 16 feet measured horizontally. In Crete, gliders are believed to have
been released at not more than 2 to 5 miles from shore and at altitudes not
more than 5,000 feet, permitting a gliding range of 8 to 10 miles. Normally
gliders are never released directly over the objective but at a sufficient
distance so that towing aircraft need not fly over the point of attack.
While the Germans were apparently successful in glider operations in Belgium,* the
glider performance in Crete resulted in many casualties due to
premature release, short turns, navigation errors, and rocky terrain. The
troop glider, like all aircraft, is extremely vulnerable to small-arms fire
when gliding low near ground defenses. Although it is not clear how
light tanks if brought by air would be employed, it is believed that
gliderborne units are not equipped to follow up tank advance, at least
in the early stages. They lack motor transport and are, therefore, not
mobile. Darkness is also a deterrent to gliderborne operations. So far
as is known, glider attacks have been limited to dawn and dusk operations.
When a glider attack is made a part of large-scale airborne operations, it is
important that glider airdromes should not be located too near the objective, since
concentrations of aircraft are conspicuous and likely to receive attention
from hostile aircraft before the units get on their way. It is, on the other
hand, impracticable to conduct glider attacks from airdromes more
than 200 miles away. Over longer distances, decisions at the rear
take progressively longer to affect the action and thus make operation
more difficult for the pilots. Furthermore, it is desirable that troops
going into action not be kept seated in aircraft for longer than 2 or 3 hours, the
time required for the 200-mile flight. Finally, since dawn is the usual
time of attack, and such attacks cannot be made unless the planes take
off at night, it would follow that they should depart early in the day
and not spend too much time on the journey.
