DEFENCE TECHNOLOGY REVIEW | ISSUE 12 | AUG 2015
The Royal Thai Navy (RTN) has made
the decision to acquire three 3,600 tonne
Yuan-class (Type 039A) diesel-electric
submarines from China at a total cost of
THB36 billion (AUD$1.41 billion).
Live firing trials of the new 40mm two-
man turret for the British Army’s Warrior
infantry fighting vehicle (IFV) have been
undertaken on a UK Ministry of Defence
range at Kirkudbright, Scotland, as part
of the Warrior Capability Sustainment
The WCSP, which has Lockheed Mar-
tin UK as prime contractor, involves the
upgrade of 380 Warrior vehicles with
new turrets, an updated environmental
control system to improve crew comfort in
climatic extremes, better camera-based
situational awareness, a driver’s night vi-
sion system and a fitting system on the
hull exterior to enable rapid change out
of appliqué armour according to prevail-
ing threat levels. Around 250 IFV variants
will receive the new 40mm turret.
The ‘WCSP Fire on the Move’ devel-
opment trials involved firing of the CTA
International 40mm Cased Telescoped
Armament System (40 CTAS) using two
40mm ammunition natures at targets
ranged at approximately 350m, 650m,
900m, 1,300m and 1,500m, Lockheed
Martin UK told DTR.
The firing trials used four scenarios of
increasing complexity to iteratively test
the 40 CTAS and turret. These were:
static vehicle on static target, moving
vehicle on static target, static vehicle on
moving target, culminating in a moving
vehicle on moving target scenario.
The turret is of a new design by Lock-
heed Martin UK instead of the originally

First export order
for V-22 Osprey
Thailand’s armed forces have held a
long-standing preference for procuring
much of their military equipment from
the West. Previous poor experiences
with the reliability and performance of
Thailand bound. A Yuan-class
submarine of the PLA Navy.
Chinese-built platforms, such as the
RTN’s two Type 25T and four Jianghu
III-class frigates, have also likely colour-
ed the perception of many in the armed
forces about the quality of military equip-
ment from China.
Despite this, RTN Command-
er-in-Chief Admiral Kraisorn Chansuvan-
ich announced the selection of the Yu-
an-class on 2 July, saying that the RTN’s
procurement committee voted 14-3 in
favour of the Chinese option in June.
The proposed procurement will now go
before Thailand’s military junta-led Cabi-
net for funding approval.
A modified export version of the
Yuan-class, the design will be desig-
nated S26T in RTN service. The first
S26T is planned for delivery within six
to seven years.
The selection of the Yuan-class comes
at the expense of offers from France,
Germany, Russia, South Korea and Swe-
den, and has further widened the divide
between Thailand and the US following
the coup which overthrew the Govern-
ment in May 2014. – Ian Bostock
The Japanese Self-Defense Force
(JSDF) is to be the first export customer
for the Bell Boeing V-22 Osprey tilt-rotor,
with five Block C versions of the aircraft
to be supplied under a US$332.5 million
(AUD$450 million) Foreign Military Sale
The five aircraft are expected to be the
initial tranche of up to 17 MV-22s in total,
the acquisition of which is part of Japan’s
medium-term defence plan.
With Israel until recently expected
to be the first international operator of
the V-22 until the plan for six aircraft
was shelved by the Government in late
2014, the JSDF will operate the tilt-
rotors predominantly off the navy’s two
Hyuga-class helicopter carriers and
three Osumi-class amphibious transport
The MV-22 will address shortfalls in
the JSDF’s existing helicopters to de-
ploy to many of the outlying islands and
territories and provide support for hu-
manitarian and disaster relief missions.
The increased speed and range of
the MV-22 compared to helicopters will
augment Japan’s amphibious capabili-
ties and no doubt support limited power
projection and response options against
the backdrop of increasing Chinese as-
sertiveness over territorial claims in the
East China and South China Seas.
The five MV-22s for the JSDF are
scheduled for delivery by June 2018.

planned modified turret. In addition to
the 40 CTAS, the turret for Warrior IFV
features independent sights for the com-
mander and gunner, a 7.62mm co-axial
machine gun and two four-round banks
of smoke dischargers.
It replaces the original turret armed
with an unstabilised 30mm L21A1
“These successful trials demonstrate
both the accuracy and lethality of the
new generation Warrior, which has been
designed and manufactured in the UK.
This is the latest in a number of trials
that have increased confidence in these
modifications,” Alan Lines, vice president
and managing director, Lockheed Martin
UK, said in a statement on 20 April.
The company plans to conduct a crit-
ical design review of the new turret in
late 2015. Vehicle reliability trials are
due to take place from first quarter 2016
through to 2017.
Lockheed Martin UK is also the turret
integration authority for the new General
Dynamics Scout SV for the British Army,
which also incorporates the 40 CTAS in
a new Lockheed Martin UK turret.
Manufacture of turrets for both the
Warrior and Scout SV programs will take
place at Lockheed Martin UK’s new pur-
pose-built facility at Ampthill, north of
London, construction of which is due for
completion in early 2016.
On 1 July, the UK Ministry of Defence
placed a £150 million (AUD$319.4 mil-
lion) order for 515 cannons for the 40
CTAS for both the WCSP and Scout SV
