On the mend: British Army looks to refreshed AFVs

After many years of underinvestment, the UK is injecting significant funding into its land forces over the
next decade, most of it being spent on the British Army's Ground Manoeuvre capability. Christopher F
Foss reports on the three major programmes
Over the last few years the United Kingdom has had many false starts in its efforts to replace or upgrade a
major part of its armoured fighting vehicle (AFV) fleet.
Many of the current vehicles were designed over 30 years ago and some are much older, soldiering on as a
succession of projects - the Future Family of Light Armoured Vehicles (FFLAV), Tactical Reconnaissance
Armoured Combat Equipment Requirement (TRACER), the Boxer Multi-Role Armoured Vehicle (MRAV) and
most recently the Future Rapid Effect System Utility Vehicle (FRES UV) - all fell by the wayside. Some were
cancelled as operational requirements changed, some died as partner countries fell out, and others as
funding was reprioritised elsewhere.
Things are looking up, however, as today two key British Army programmes are well underway in the shape
of the General Dynamics UK (GDUK) Scout - Specialist Vehicle (SV) and the Lockheed Martin UK (LMUK)
Warrior Capability Sustainment Programme (WCSP). In addition, work is also firming up on a competition
for the Challenger 2 Life Extension Programme (LEP), a resurrected UV requirement, an Armoured
Battlegroup Support Vehicle (ABSV), and Mine-Resistant Ambush Protected (MRAP)-type vehicles, which
were urgently procured for operations and are now being modified and standardised to be brought into
the core British Army equipment programme.
Of all these, the biggest and most far-reaching is arguably the Scout SV. GDUK scooped the prize of a
GBP500 million (USD775.35 million) contract (including taxes) in July 2010, funding a demonstration and
qualification phase of a vehicle project to replace the remaining members of Alvis Vehicles' Combat Vehicle
Reconnaissance (Tracked) family. The latter includes the Scimitar reconnaissance vehicle, which was
accepted for service with the Royal Armoured Corps (RAC) in 1973.
Scout SV has evolved and GDUK is currently building a total of seven prototype SVs for trials and
evaluation, all of which should be running in 2016.
In support of this, a representative mule known as the Mobile Test Rig (MTR) was completed at the
General Dynamics European Land Systems - Steyr (GDELS - Steyr) facility in Vienna, Austria, in May 2012,
providing a platform to de-risk the programme, in parallel with suspension and powerpack rigs.
The MTR conducted shakedown trials in Austria and then headed to Spain for a comprehensive suite of
durability trials, pounding around GDELS' off road circuit near Seville with growing weights and loads. Since
then, the MTR has undergone a whole battery of testing, including cold weather and Operational and
Tactical (O&T) mobility trials.

LMUK is developing the two-person turret for the vehicles, under contract to GDUK, alongside a separate
project to develop a new turret under the WCSP. Both turret types are armed with the CTA International
40 mm Case Telescoped Cannon (CTC) provided as government furnished equipment (GFE).

Scouting for performance
Once in service, the Scouts should offer a step change in tracked reconnaissance capability over the old
CVR(T)s. The size of Scout SV raised the eyebrows of some more used to the petite dimensions and
cramped interior of Scimitar, but it will offer far greater protection than the legacy platform and its new
sensor system is a world away, promising seamless distribution of video and data around the vehicle's own
network and across the battlefield, or beyond.
It is essentially a further development of the ASCOD (Austrian Spanish Co-Operative Development) to meet
specific UK requirements and the baseline welded-steel armour hull weighs about 22.3 tonnes without its
advanced armour package (GDUK and the MoD are very sensitive about the exact classification of the
vehicles' protection levels and have refused to specify them in open source, saying only that it is high). The
family of vehicles is spun off a Common Base Platform (CBP) to reduce through-life costs, all sharing the
same baseline hull design, powerpack, final drive, suspension and running gear, driver's station, CBRN and
Environmental Control System, main and secondary fuel tanks, and battery box.
All of the vehicles are also outfitted with GDUK's generic vehicle architecture (GVA)-compliant Electronic
Architecture, easing upgrades and maintenance, as well as distributing control and management of all
platform systems and maximising common components.
Mindful of operational experience in Afghanistan and Iraq, the MoD specified the vehicle with uprated
protection against mines and improvised explosive devices (IEDs). Scout SV features a concave
homogenous hull floor, with integral composite panels adding lightweight protection, and all crew
members are provided with roof-mounted blast-attenuating seats.
The standard Scout SV's overall layout is conventional, with the driver on the front left and the powerpack
to the front right, the two-person turret in the middle and additional space at the rear, though the other
role specific versions vary slightly.
The powerpack comprises MTU's 8V199 diesel engine as used in the 8x8 Boxer MRAV, but in an uprated
configuration with an improved intake and two-stage pulse jet air cleaner enabling it to develop 600 kW
(800 hp), 70 kW more than the German installation. Power is delivered to the tracks through a Renk 256B
fully automatic transmission, affording the driver a relatively easy carlike interface. Based on the vehicle's
stated gross vehicle weight (GVW) of 38 tonnes, the Scout's power-to-weight ratio of 21 hp/tonne is
sufficient for a maximum road speed of up to 70 km/h.
More power is available with further tuning to account for inevitable hikes in combat weight. As it stands,
Scout SV will have a combat weight of 34 tonnes but will be rated at 38 tonnes with a clearly defined
stretch potential to 42 tonnes.
GDELS SBS recently awarded an EUR80 million contract to Rolls-Royce Power Systems covering the supply
of 569 MTU engines (20 engines shy of the full vehicle-production contract) for the Scout programme
between 2016 and 2022. The contract also includes the cooling system and two generators per set, with a
total capacity of 550 Amps.

As well as the extra power, Scout SV has a significantly upgraded dual-rate suspension system over the
original ASCOD design, combining torsion bars and hydraulic dampers to provide an improved ride for the
crew and a more stable firing platform over rough terrain.
Most of the Scout's actual performance is resident in the turret, of course, and LMUK's design has a
relatively traditional layout, at least regarding the crew, with the commander seated on the right and the
gunner on the left. Each location has a roof hatch and access into the hull via the lower part of the turret
basket.
Like the hull, the turret is made of all-welded steel with ballistic protection to match, and attachment
points for passive appliqué plate. It sits on a large turret ring with a diameter of 1.7 m, which can be
expanded to 1.9 m, enabling it to take a turret armed with a 120 mm smoothbore gun.
The Scout's standard 40 mm CTC configuration enables the gun to be mounted externally, providing more
space in the turret than is possible with a traditional cannon. Extensive firing trials are exploring its
capabilities, but the advanced fire-control system (FCS) and stabilisation should enable the cannon to
accurately engage stationary and moving targets, whilst on the move, in almost all weather conditions.

Warriors' rise
GKN Defence's (now BAE Systems Combat Vehicles UK) Warrior infantry fighting vehicle (IFV) has been the
mainstay of the British Army's mechanized forces since 1988, with 789 vehicles delivered. It has seen
service in the Balkans, Iraq and Afghanistan, undergoing a range of upgrade programmes and theatre entry
modifications over the 20 years since the last Warrior was handed over to the army.
The final Warrior urgent operational requirement (UOR) upgrade saw 70 vehicles grafted with equipment
to Theatre Entry Standard (Herrick) by the then-Defence Support Group (today Babcock International)
under BAE Systems Combat Vehicle UK as the overall design authority. As a result of these spiral and
theatre-specific upgrades, the MoD now has a mixed force of vehicles and has decided to rebaseline them
all on a common standard under the WCSP, extending their operational lives to keep them in service until
2035/2040.
Following a hard-fought competition LMUK beat BAE Systems to selection and was awarded a WCSP
Demonstration contract in November 2011, which also includes an option for manufacture. Work is well
underway on the demonstration phase, but as of August 2015, a production decision had yet to be made
and the project could still therefore theoretically dissolve, though the army would then need to urgently
address shortcomings in the platform and plot a new route to provide its mechanised infantry with
protected mobility and firepower.
The demonstration contract was initially worth around GBP200 million and production was estimated at
GBP642 million (excluding taxes), but as a result of contract amendments the value of the demonstration
phase has now increased to around GBP225 million and the value of the still to be awarded manufacturing
contract could also increase in the future. The total value of the WCSP - including MoD costs and GFE - is
currently hovering at around GBP1 billion, though the National Audit Office has cited expectations that it
may rise by around a third.
Production of the new WCSP turret will be undertaken at a new GBP5.5 million facility currently being built
at LMUK's facility at Ampthill, Bedfordshire, where research, development and prototype facilities have

been operational for two years, and where the first turrets were built. This facility will be completed early
in 2016 and bring the total invested by LMUK at Ampthill - near the Millbrook Proving Ground - up to
around GBP23 million over the last 10 years.
The Warrior hulls will be upgraded under WCSP when they go through their base overhaul at the Babcock
International facility at Donnington, which has extensive experience in Warrior maintenance, support and
upgrade work. Plans have changed over the years (with the sale of Defence Support Group in particular
adding some ambiguity), but as of July 2015 LMUK is planning to integrate the hull and turret at Babcock
International in Donnington.
While the programme has been subject to change and movement of schedule, additional vehicles and
turrets have been added to further de-risk the programme as much as possible and LMUK is confident that
the latest in-service date of 2020 will still be met.
WCSP is a holistic project encompassing the Warrior Fightability & Lethality Improvement Programme
(WFLIP), Warrior Enhanced Electronic Architecture (WEEA) and the Warrior Modular Protection System
(WMPS).
If all goes to plan, it is expected that 380 Warrior IFVs and variants will be upgraded through WCSP with
around 285 fitted with the new turret.
In the early private venture development phase LMUK planned to reuse the original Warrior IFV two-
person turret, designed and built by then-Vickers Defence Systems to house the unstabilised and slow-
firing L21A1 30 mm RARDEN cannon, but modified for the new 40 mm CTC. However, that turret's size
proved ultimately too constraining and the company ended up designing a brand new two-person turret
offering more volume and easier integration of all of the sub-systems, along with greater stretch potential.

Clinging on
For an army that pioneered the use of tanks, the British Army has not been overly precious about
protecting its once-vaunted Challenger 2s' operational edge.
Perhaps more than any other British AFV, the Challengers have suffered from under-investment and a lack
of direct operational requirement for main battle tanks (MBTs) after the initial invasion of Iraq saw their
numbers cut and capability dwindle. A situation not helped by the development cul-de-sac of the L30A1
rifled gun, which limits their reach and lethality, leaving them theoretically outmatched by many other
tanks on the battlefield.
The lethality of the gun firing the CHARM 3 armour-piercing fin-stabilised discarding (APFSD) round with a
depleted uranium penetrator against some potential armour threats must now be in question, a situation
compounded by a lack of interoperability with other allied MBTs armed with a 120 mm smoothbore gun.
After a series of fits and starts, however, it appears that the army is poised to commit to a Challenger life-
extension project, albeit in a lesser form than a full capability upgrade as being developed for Warrior.
Vickers Defence Systems built a total of 386 Challenger 2 MBTs for the British Army at its Leeds and
Newcastle-upon-Tyne facilities, with final deliveries made in April 2002. Both of these facilities have now
closed, but BAE Systems Combat Vehicles UK retains a core Challenger 2 post-services team in Newcastle

and Telford, which also provides support to the Challenger Armoured Repair and Recovery vehicle, Titan
AVLB, and the Trojan engineer vehicle.
The Challenger 2s were expected to have been upgraded under the Capability Sustainment Programme
(CSP) in the mid-2000s - including a Challenger Lethality Improvement Programme (CLIP) to install
Rheinmetall's L/55 120 mm smoothbore gun - but the programme slipped and disappeared from view.
The CLIP principle was actually tested in a Challenger 2 by the Armoured Trials and Development Unit
(ATDU) at Bovington in 2005/2006 under the 120 mm smoothbore Technology Demonstrator Programme
(TDP), but there are no current plans for this to be backfitted into the remaining Challenger 2 MBT fleet.
While discussions were going on to enhance and sustain the tanks, about 120 of them had been deployed
to Kuwait ahead of the invasion of Iraq, and like the Warriors, these vehicles went through a series of
upgrades with BAE Systems in the Kuwaiti desert to counter anticipated - and then experienced - threats.
The force was slimmed down to one squadron in Basra throughout operation 'Telic', but those tanks were
continually upgraded as a series of in-country UORs by BAE Systems.
This UOR package covered additional armour (including underbelly plates after one tank was damaged by
an RPG as it climbed a ramp and another was penetrated by an IED), a Selex Enforcer roof-mounted
remote weapon station (RWS) armed with 7.62 mm machine gun to enable the crews to fire from under
armour, wire cutters, upgraded cooling, a modified air cleaner for the powerpack, new driver night-vision
devices, reverse cameras, and electronic devices to counter IEDs.
Together, these systems steadily pushed the GVW of the Challenger 2 up from just over 60 tonnes to
around 75 tonnes. As a result, the Challenger 2's power-to-weight ratio compares poorly to other MBTs
deployed by NATO, such as the Leopard 2, Leclerc, and M1A1/M1A2 Abrams.
As with the Warrior project, the upgrade work and mothballing resulted in a mixed fleet of Challenger 2s
and in mid-2013, the MoD confirmed that it was working on a Challenger 2 Life Extension Programme (LEP)
- as the name suggests a more austere project, with less ambitious scope than the CSP - that would
standardise the remaining vehicles in a more cohesive configuration. This coincided with a significant
reduction in strength, with the number of available vehicles now reduced to 227, with 58 nominally issued
to each of the three Royal Armoured Corps regiments. However, under the Joint Asset Management and
Engineering Solutions (JAMES) scheme, they normally only have one squadron for day-to-day training with
the rest kept in reserve for units deploying on operations.
As well as the standardisation and maintenance elements, the project aims to replace obsolete sub-
systems such as optronics and GCE. Many of those sub-systems were designed over 25 years ago - as
design work on the Challenger 2 can be traced to 1987 under private venture funding by Vickers Defence
Systems - along with all of the attendant computing limitations and pitfalls that this implies.
As Vickers was absorbed into BAE Systems Combat Vehicles UK, the company retains the overall design
authority for Challenger 2, but the MoD stated to IHS Jane's that the ministry "has the capacity to meet all
future upgrade requirements", which is being interpreted as a plan to possibly award the work elsewhere
with no involvement for BAE Systems. In line with this, the Defence Equipment and Support organisation is
to hold a competition for the LEP and there are expected to be at least three bidders in addition to BAE
Systems: GDUK, Krauss-Maffei Wegmann and LMUK.
Requests for information (RfI) were issued to industry in 2014 with a Pre-Qualification Questionnaire
expected later in 2015 and an Assessment Phase Invitation to Tender in 2016.

The original out-of-service date of Challenger 2 was expected in 2028, but this has been progressively
pushed to the right and is now around 2035 (pending the LEP work).
