Warrior in “Wrap-2” armor
(click to view full)

Britain’s MCV-80/FV510 Warrior Infantry Fighting Vehicle was produced between 1984 and 1995. Built of all-welded aluminum construction and armed with the 30 mm Rarden cannon, it was designed to be a fast, armored battlefield taxi for up to 7 infantry soldiers, capable of offering strong supporting fire and destroying enemy armored personnel carriers at ranges of up to 1,500m. These IFVs were pressurized to protect against Soviet chemical and biological weapons, and included a full range of night vision equipment. They served capably during Operation Desert Storm in 1991, were used to maintain the peace in Bosnia/Kosovo, and have found themselves in very high demand on the post 9/11 front lines.

Individual programs have improved some vehicles’ optics, radios, and add-on armor, but keeping the fleet in service until 2035 will require more. Hence the GBP 1 billion (currently about $1.65 billion) Warrior Capability Sustainment Programme (WCSP).

In mid-November 2009, BAE Systems and Lockheed Martin UK submitted their bids…

WSCP Program, Technologies, and Bid Teams

Basic Warrior IFV

The WCSP effort has 4 main sections; WFLIP (Warrior Fightability Lethality Improvement Programme) to improve turrets and sensors, and add firepower; WMPS (Warrior Modular Protection System) to add a modular armoring system; WEEA (Warrior Enhanced Electronic Architecture) to add a fully integrated set of modern, expandable electronics and communications gear; and ABSV (Armoured Battlefield Support Vehicle) to improve the repair and recovery variants that keep the fleet in the field.

Out of 789 Warrior IFVs received by the British military between 1987 – 1995, WCSP will upgrade 643 vehicles with WEEA electronics and WMPS modular armoring upgrades. Within that group, 449 vehicles will also get WFIP program’s new turret and weapon system. The remaining Warriors will be turretless, and carry out field repair and recovery roles using winch and crane attachments.

The core of the WFLIP weapons program will be a new gun, paired with an automated ammunition feed instead of manually-loaded 3-round clips. It will be mounted in a new, stabilized turret, capable of firing accurately on the move, and linked to advanced sensors, modernized targeting systems, and a built-in defensive aids suite. If it works, the gun could offer a system that combines 25mm gun and ammunition space requirements with 50mm gun punch.

The UK Ministry of Defence mandated the CT40 CTWS (cased telescoped weapon system) and its 40mm ammunition for both Warrior WCSP and Britain’s forthcoming FRES-SV scout vehicle. The system is produced by CTA International (CTAI), an Anglo-French joint venture between BAE Systems and Nexter. It fires a 1 kg HE (high-explosive) round with 3 times the terminal effect of the 30mm Rarden shell, and its high explosive air burst (HEAB) capability allows detonation in mid-air at precise ranges. This is very useful for dealing with urban strongpoints like a room inside a reinforced building, or enemies hiding behind cover.

The system’s most unusual feature, however, is its ammunition – a projectile encased inside a cylinder, with the propellant packed around it. That cuts round length by about 50%, and improves volumetric efficiency by about 33% for a given level of performance. Storage space is always at a premium, and these efficiencies remove some of the natural penalties that accompany a larger 40mm gun. Telescoped ammunition also allowed CTAI to replace the normal breech arrangement with a static ammunition feeder that feeds into a novel rotating breech design, via a hollow trunion. Practical advantage include a feeder with less than 50% of the number of parts found in a standard system, and which can be located farther forward, out of the crew’s way.

Despite this compartmentalization of the WCSP, the process must also be managed holistically. As BAE Systems’ Warrior campaign director Judith Eastwood, points out, changes in one area lead to changes elsewhere:

“For instance, as Warrior weight has grown, we have developed better brakes. These generate extra heat, which has to be managed to avoid knock-on effects.”

And so forth. Despite general agreement on that point, however, the competing bids represent different philosophies.

BAE touts the need for a new turret into order to provide optimum structural integrity, protection and crew exit, and human design for the crew. BAE sees less value in keeping the Warrior’s exact current chassis; for instance, crew stations and hatches were re-designed to accommodate the extra bulk of infantry body armor, which has become ubiquitous in recent years and can make it hard for troops to escape imperiled vehicles.

BAE’s WEEA offering is very similar to the open architecture system that BAE Systems is offering for is CV90 FRES SV, while its WMPS solution will provide a standard mounting system for the various armor fits that have been developed for the Warrior under recent UORs. A new blast-attenuating driver’s will improve earlier UOR (Urgent Operational Requirement) mine protection measures, such as a new belly plate and stiffer suspension to restore the vehicle’s ride height.

BAE is not discussing its WCSP team members, except to say that the UK’s DSG will play a prominent role:

“DSG (the government-owned Defence Support Group) already does base repair and overhaul for Warrior, so it would make sense for them to carry out the upgrade at the same time. We already work with them on most of our vehicles (including Warrior) and the UK AFV Strategy strongly suggests that their facilities should be used where possible.”

On the other side, Lockheed Martin UK touts the virtues of a WFLIP turret that’s a modified version of the current system. They point to lower acquisition costs by avoiding significant hull modifications, and better whole life costs from reuse of existing spares stocks. Their upgrade is designed to be achieved while part of the Warrior Base Overhaul process done by the UK Army Base Repair Organisation (ABRO, which was later merged into the DSG).

Lockheed Martin UK’s 13-firm Warrior Transformation team includes:

• UK’s Defence Support Group (and see Nov 19/09 strategic partnership entry)
• CTA International (gun, ammunition handling)
• Curtiss-Wright Antriebstechnik GmbH (electro-mechanical turret drive and stabilization system)
• Moog (rotary base junction)
• NP Aerospace
• Rheinmetall Land Systems (turret design, cannon mounting)
• SciSys (electronic architecture)
• Thales Optronics (commander and gunner sights)
• Ultra Electronics

Dec 15/09: Lockheed Martin UK announces that their team has successfully tested its design for the Warrior Capability and Sustainment Programme (WCSP) in a series of limited live firing trials, at the QinetiQ Test Range in Shoeburyness, Essex, UK. These tests were designed to prove structural integrity, accuracy, and integration. See also Dec 3/08 entry.

Nov 19/09: Lockheed Martin UK signs a Strategic Partnering Agreement (SPA) with the UK government’s Defence Support Group (DSG). It provides an overarching partnership framework that sets out key terms between the 2 organizations, which will be supplemented by specific teaming agreements, as opportunities arise. Specific teaming agreements for the Warrior Capability Sustainment Programme (WCSP) and the Future Rapid Effect System (FRES) are part of the initial SPA. Lockheed Martin adds that:

“This Strategic Partnering Agreement underpins Lockheed Martin UK’s commitment to the Armoured Fighting Vehicle (AFV) Sector…. Our plan, if we are successful in our bids on the WCSP and FRES programmes, is to co-locate with DSG at their Donnington facility.”

DSG launched on April 1/08 and brought together the Army ABRO and Navy/RAF DARA trading fund organizations into a single new defense Trading Fund, whose primary focus is in providing expert in-house maintenance, repair, overhaul and upgrade services for the through-life support of UK Armed Forces equipment. DSG’s Head Office is located in Andover and provides strategic direction to the main sites in Bovington, Catterick, Colchester, Donnington, Sealand, St Athan, Stafford, Stirling, Telford and Warminster. Smaller support sites are located in Aldershot, Bicester, Kinnegar and Sennybridge ; and small support teams are permanently embedded at other UK military sites, as well as supporting operations at home and abroad.

Nov 17-18/09: BAE Systems and Lockheed Martin UK submit bids for the WSCP program, and offer details concerning their solutions and/or teams. A decision is expected in Q1 2010.

BAE Systems touts their delivery of over 40 Urgent Operational Requirement (UOR) modifications for Warrior in the last 5 years, and investment of GBP 40 million in company funds to develop the new gun, a new turret, and the vehicle’s electronic architecture.

Lockheed Martin UK’s release mentions its team of partners, and the firm provided additional details in response to questions; these were incorporated into the background briefing, above.

March 30/09: Defense News reports that Britain and France have agreed to a common process to qualify CTAI’s CT40 gun and ammunition, as the culmination of a 15-year, EUR 100 million development effort by the BAE Systems/ Nexter joint venture. Testing is expected to involve around 20,000 rounds, and could clear the cannon and most of its ammunition types for action by 2012.

Dec 3/08: BAE Systems announces the successful completion of a demonstration and trials at the Kirkcudbright range in Scotland, using their MTIP2 40mm turret and its Cased Telescoped Armament System (CTAS). MTIP2 is a BAE Systems-funded project to lower risks for both both the Warrior Fightability and Lethality Improvement Programme (WFLIP) and the FRES-SV Scout vehicle. While the company’s offerings will use different turrets, they’ll share many common systems. BAE:

“Over the course of 3 trials open days, visitors saw the system perform static and moving firings against static and moving targets, using both training and armour-piercing rounds. 90 rounds were fired from the 40mm gun and 600 rounds from the chain gun [coaxial machine gun], achieving high levels of accuracy and reliability.”

March 26/08: The British MoD decides that Warrior WFLIP and FRES-SV will use the Nexter/BAE CT40 gun and ammunition system. The design beats out Finmeccanica’s HITFIST-30 2-man turret with ATK’s Mk.44 30mm gun; and General Dynamics UK’s MK46 turret with Mk.44 gun as developed for the USMC’s amphibious EFV. Lockheed Martin Insys’ is designing a turret based on the existing Warrior design, adapted by Germany’s Rheinmetall Landsysteme. It was also reportedly slated to use the Mk.44, but the firm claims that its design is weapon-agnostic, and intends to continue competing. Jeffrey Strategic.

Dec 5/07: Lockheed Martin UK announces successful testing of its WFLIP turret design, which combines ATK’s Bushmaster 30mm Mark 44 Cannon, on a modified Warrior turret with a dual axis stabilized BGTI sight from Thales Optronics Limited. Rhinemetall Defence has designed the cannon, the mounting structure and the Ammunition Handling System. Curtiss-Wright is responsible for the turret stabilization.

The series of limited live firing trials was conducted at the Cranfield Ordnance Test & Evaluation Centre on Salisbury Plain Training Area. Through rapid prototyping Lockheed Martin has taken its WFLIP turret from an idea, through concept design, physical prototyping to live firing in just 33 weeks.
