Italeri 1/35 MAS 568 serie 4a
Originally conceived in 1915 as a small coastal torpedo boat, the early
prototypes were failures. This was largely due to the excessive weight of the
stern-positioned torpedo tubes which kept the speed well below 20 knots,
relegating the the first two boats to mine laying duties.
World War I saw vast improvements in fast small patrol craft, 20 boats were
ordered for coastal anti-submarine duties. Wartime technology requirements
resulted in no less than 244
boats entering service with the Regia Marina.
These advancements in maritime technology resulted in the development of the
SVAN 12t type – the first true torpedo
which gained considerable fame when Commander Luigi Rizzo sank the Australian
Battleships Wien and Szent Istvan on
During the 1920s and 30s speed was considered the principle factor in
Italian torpedo boat design.
shape design and more powerful engines resulted in the much sought after goal of
40 knots achieved by
424 in 1928. Four boats were fitted with three 500hp Isotta Fraschini Asso
engines which akso included the first use of the ‘Side impulse’ 450mm torpedo
launcher which would be a feature of the Italian boats up to the 1970s.
The new 1935 Baglietto project craft, considered the first ‘true’ 500
craft was designed with a 17 metre long, 4.4m wide planning hull with two steps
and twin 1,000hp ASM180 engines producing speeds in excess of 45 knots. An order
was quickly placed for 24 boats (MAS
501-524). Production started in five different yards, with the first boat (MAS
509) launched on
February 15th, 1936.
Tests proved that the boats performed as expected. All of the 24t boats reached
45 knots; the fastest (MAS
524) reached a top speed of 51.6 knots!
Teething troubles delayed delivery of the
boats to the Regia Marina.
501 was finally ready in in January 1937, armed with two torpedoes and two
13.3mm machine guns. Amongst the early modifications the bow 13.2mm was
discarded as its use had proven problematic at high speeds. A better
longitudinal weight distribution was achieved by re-positioning the torpedo
launchers in a ‘nose up’ position
The 25th and final 1a serie boat (MAS
525) was delivered in October 1937; this differed from other boats in the series
in having a metallic hull. Though lighter than its wood-hull counterparts
performance was similar.
The 3a serie (MAS
551-564) was ordered in May 1940. It was broadly similar to the 2a serie with
the exceptions of a
’35 20mm MG, reinforced stern and a flying bridge steering wheel. The fuel load
displacement was 29t and four boats of this series had metallic hulls. Compared
to the 3a, the 4a serie (MAS
566-576) only had minor detail differences; all featured wooden hulls. The final
570) was delivered in October 1941.
The performance of the ‘500s’ at war was severely limited by sea
conditions. Planing hulls meant that the high speeds deemed necessary for a
successful torpedo attack could only be reached in calm weather. Nevertheless a
few important operations saw these boats involved against British shipping in
the Mediterranean area. In the night between August 12th and 13th
1942, 13 2a and 3a serie boats attacked the ‘Pedestal’ convoy bound for
together with six Italian heavy torpedo boats and four German Schnellboote.
Successes by ‘500s’ included the sinking of two transports, the Wairanghi
Lykes and the damage of two more.
It was on the Eastern front on
that the ‘500’ series met ideal operating conditions. In mid-1942 the 12a
525-529) were deployed for operations against Soviet shipping. Intense activity
over the summer resulted in the sinking of a gunboat and several transports. The
four boats were finally sold to the Finnish Navy in June 1943.
A total of 10 ‘500s’ were deployed to the black sea from April 1942;
attacked Soviet shipping in the
568 heavily damaged the cruiser Molotov and sank a transport.
571 sank a submarine,
573 another transport. Plans to deploy four of these craft to the
came to nothing. And in May 1943 the surviving boats went to the Kriegsmarine
and later to the Romanian Navy.
The box art depicts a suitably exciting scene which implies great promise
for the contents. I have made Italeri’s Vosper
80’ and the
were similarly well packaged with the hull semi-recessed into a card tray with
card folding retainers and the parts stored in polyurethane bags. I shouldn’t
have been surprised at the size of the
but having made two other boats in Italeri’s 1/35 series, this kit is small.
Nevertheless, the subject is a welcome edition and the parts are cleanly moulded
in a crisp, grey plastic. The deck detail is subtle enough without being too
overpowering and an initial dry-fit showed great promise (despite their being so
There are 164 parts in total, when compared to the 395 parts included in the
you can almost see my point. The instruction booklet is clear and concise and as
always the photographic reference booklet is an invaluable reference source.
This kit was kindly supplied by Spot-On Models and Hobbies of Swindon as part of
their window display. It looks impressive with the
77’ and the
80’, the comparison between the boats is quite dramatic.
As with all of these large Italeri boats, I cannot fault the construction
process. They really are a joy to make. The hull and deck are constructed first,
take care to refer to the drilling diagram when drilling the locating holes in
the deck. After pre-assembling the upper-works the completed hull and
sub-assemblies were primed in grey primer and left to dry over-night. The cabin
was constructed and deck-fittings mounted before the model was pre-shaded in
matt black. All deck accessories were painted prior to fitting.
Markings are provided for two options, Regia Marina,
568 Garzuf (Yalta) Black Sea (Russia), summer 1942. And the option that I
decided upon: Regia Marina,
563, Mazara del vallo, Italy 1943 as
it includes the red and white identification stripes on the deck. For
colors I used Humbrol
Matt 34 White and White Ensign Models Rosso (RM 08) for the forward deck
identification markings. White Ensign Models Grigio Chiaro (Light Grey RM 02)
for the upperworks and the hull and White Ensign models Grigio Scuro (Dark Grey
RM 01) for the deck and the below the waterline.
This is a beautifully crafted kit, with some after-market accessories and
crew set this torpedo boat could be made into a real show stopper. Highly
