The Puma is a German infantry fighting vehicle (Schützenpanzer or short SPz) designed to replace the aging Marder IFVs currently in service with the Bundeswehr. Replacement began in 2010 and is scheduled for completion by 2020. Mass production began on 6 July 2009. The company responsible for the project is PSM Projekt System Management, a joint venture of Krauss-Maffei Wegmann and Rheinmetall Landsysteme. The Puma is one of the best-protected IFVs, while still having a high power-to-weight ratio. SAIC offered a derivative of the Puma as its contender in the American GCV Infantry Fighting Vehicle program.
The Puma (formerly also named Igel (hedgehog) and Panther) started as a follow-up project to the German mid-1990s "NGP" project (Neue Gepanzerte Plattformen, "New Armored Platforms"). Its aim was to collect ideas for a common base vehicle that could be used for a variety of tasks including that of the APC, IFV, air defense and replacing and assisting the MBT in the frontline combat role. The NGP project was ended in 2001.
The lessons learned were incorporated into the new tactical concept named neuer Schützenpanzer ("new IFV") in 1998. In 2002, the German Army (Heer) placed an order for the delivery of five pre-production vehicles and their logistics and training services at the end of 2004. On 8 November 2007, a budget of €3 billion to acquire 405 Pumas (excluding the five Pumas that had already been delivered to the German Army for trials) was agreed upon.
Other nations pursue similar developments emphasizing commonality, modularity and rapid deployability based on a comparable doctrine which was also a subject of discussion within NATO. Examples of these are the American GCV Infantry Fighting Vehicle, the British FRES and the German-Dutch Boxer MRAV.
On 6 December 2010, the first two serial vehicles were handed over to the German Bundesamt für Wehrtechnik und Beschaffung.
The Puma successfully completed cold tests in Norway in 2012. In August 2013, two Pumas were airlifted to the United Arab Emirates for hot weather tests. Trials included suitability for hot weather operations, firing and driving maneuvers in desert conditions, as well as firepower and mobility evaluations. During the trials, the temperature profiles inside the vehicle were measured, then compared to the ambient temperature.
On 13 April 2015, the Federal Office of Bundeswehr Equipment, Information Technology and In-Service Support (BAAINBw) granted authorization of use of the Puma IFV. This began a program to "train the trainers" on the first seven vehicles and additional ones until the end of the year, when a training center will be set up to put Panzer Grenadiers of mechanized infantry companies through a three-month course to familiarize them with their Pumas. The Puma officially entered service with the German military on 24 June 2015.
Given the advanced age of the current Marder IFVs, and because the world market does not offer any vehicle comparable with the specifications to which the Puma is built, the acquisition of the new vehicles has been unanimously voted for by the budget committee of the Bundestag.
The delivery of 350 Pumas, replacing the more than 40-year-old Marders, is expected to be completed by 2020.
There are provisions for hard- or soft-kill systems to defeat hostile ATGMs or RPGs, or for future active/reactive armor. There are also mounts and interfaces for the inclusion of ATGMs on the right side of the turret.
Its large weight reserves and the compact cabin make it very attractive for modification. Most vital integrals are situated in the front, floor, and side walls, which may remain unchanged during such a cabin-oriented modification.
The Puma, while externally not very different from existing IFVs, incorporates a number of advances and state-of-the-art technologies. The most obvious of these is the incorporated ability to flexibly mount different armour (see below for details). Another feature is the compact, one-piece crew cabin that enables direct crew interaction ("face-to-face"; like replacing the driver or gunner in case of a medical emergency) and minimizes the protected volume. The cabin is air conditioned, NBC-proof with internal nuclear and chemical sensors and has a fire suppressing system using non-toxic agents. The engine compartment has its own fire extinguishing system. The only compromise of the otherwise nearly cuboid cabin is the driver station, located in a protrusion in front of the gunner, in front of the turret.
One measure to achieve the one-piece cabin is the use of an unmanned, double-asymmetrical turret (see photo): while slightly off-center turrets are common in IFVs, the Puma's turret is on the left-hand side of the vehicle, while the main cannon is mounted on the right side of the turret and thus on the middle axis of the hull when the turret is in the forward position.
The outer hull (minus the turret) is very smooth and low to minimize bullet traps and the general visual signature. The whole combat-ready vehicle in its base configuration will be air transportable in the Airbus A400M tactical airlifter. Its 3+6 persons crew capability is comparable to other vehicles of comparable weight, like the US American M2 Bradley IFV, the same as in the Marder, but smaller than the 3+8 of the CV9030 and CV9035.
The primary armament is a Rheinmetall 30 mm MK 30-2/ABM (Air Burst Munitions) autocannon, which has a rate of fire of 200 rounds per minute and an effective range of 3,000 m. The smaller 30×173mm cartridge offers major weight saving advantages for example in comparison to the Bofors 40 mm gun mounted on the CV9040 because of a much lower ammunition size and weight. The belt feed system also gives a large number of rounds ready to fire, while the 40mm offers only 24 shots per magazine. This is not a problem in a CV9040, but would force the Puma off the battlefield to reload the unmanned turret.
There are currently two ammunition types directly available via the autocannon's dual ammunition feed. One is a sub-calibre, fin-stabilised APFSDS-T (T for tracer), with high penetration capabilities, mainly for use against medium armoured vehicles. The second is a full-calibre, multi-purpose, Kinetic Energy-Timed Fuse (KETF) munition, designed with the air burst capability (depending on the fuse setting) for ejecting a cone of sub-munitions. The ammunition type can be chosen on a shot to shot basis, as the weapon fires from an open bolt, meaning no cartridge is inserted until the trigger is depressed. The ammunition capacity is 400 rounds; 200 ready to fire and 200 in storage.
Keeping the weight within the 35-ton limit also led to a smaller calibre for the secondary armament, a coaxially mounted 5.56 mm HK MG4 machine gun firing at 850 rounds per minute and with an effective range of 1,000 m. The ammunition capacity is 2,000 rounds; 1,000 ready to fire and 1,000 in storage. While this is a smaller weapon than the western standard secondary armament (7.62 mm caliber MG), it offers the advantage that the crew can use the ammunition in their individual firearms. In situations where the lower range and penetration of the 5.56 mm rounds is an issue, the high ammunition load of the main gun enables the vehicle crew to use one or two main gun rounds instead. The gun housing can also host the 7.62 mm MG3.
To combat main battle tanks, helicopters and infrastructure targets, such as bunkers, the German Puma vehicles will be equipped with a turret-mounted EuroSpike Spike LR missile launcher, which carries two missiles. The Spike LR missile has an effective range up to 4,000 m and can be launched in either the "Fire and Forget" or "Fire and Observe" mode.
In addition to the usual smoke-grenade launchers with 8 shots, there is a 6-shot 76 mm launcher at the back of the vehicle for close-in defence. The main back door can be opened halfway and enables two of the passengers to scout and shoot from moderate protection.
The Puma was designed to accommodate additional armor, initially planning to offer three protection classes which are wholly or partly interchangeable. Protection class A is the basic vehicle, at 31.5 metric tons combat-ready weight air transportable in the A400M. Protection class C consists of two large side panels that cover almost the whole flanks of the vehicle and act as skirts to the tracks, a near-complete turret cover and armor plates for most of the vehicle's roof. The side panels are a mix of composite and spaced armor. It adds about 9 metric tons to the gross weight. Originally, there was also a protection class B designed for transport by rail. However, it became obvious that class C lies within the weight and dimension limits for train/ship transportation, thus class B was scrapped.
The Puma is protected by AMAP composite armour, the AMAP-B module is used for protection against kinetic energy threats, while AMAP-SC offers protection against shaped charges.
A group of four A400M aircraft could fly three class A Pumas into a theatre, with the fourth airplane transporting the class C armor kits and simple lifting equipment. The Pumas could be built-up to armor class C within a short time.
The basic armour can resist direct hits from 14.5 mm Russian rounds, the most powerful HMG cartridge in common use today (and up to twice as powerful as the western de facto standard .50 BMG cartridge). The frontal armour offers protection against medium caliber projectiles and shaped charge projectiles. In protection class C, the flanks of the Puma are up-armored to about the same level of protection as is the front, while the roof armor is able to withstand artillery or mortar bomblets.
The Pumas of the German Army will be equipped with a soft-kill system called Multifunktionales Selbstschutz-System (multifunction self protection system), MUSS, which is capable of defeating ATGMs.
The whole vehicle is protected against heavy blast mines (up to 10 kg) and projectile charges from below, while still retaining 450 mm ground clearance. Almost all equipment within the cabin, including the seats, has no direct contact to the floor, which adds to crew and technical safety. All cabin roof hatches are of the side-slide type, which make them easier to open manually, even when they are obstructed by debris. The exhaust is mixed with fresh air and vented at the rear left side. Together with a special IR-suppressing paint, this aims at reducing the thermal signature of the IFV.
Another crew safety measure is that the main fuel tanks are placed outside of the vehicle hull itself, mounted heavily armored within the running gear carriers. While this may pose a higher penetration risk to the tanks, it is unlikely that both tanks will be penetrated at the same time, enabling the vehicle to retreat to a safer position in case of a breach. There is also a collector tank within the vehicle, which acts as a reserve tank in case of a double tank breach.
Sensors and situational awareness
The Puma offers improvements in situational awareness. The fully stabilized 360° periscope (PERI) with six different zoom stages offers a direct glass optic link to either the commander or the gunner. Since this is an optical line, it had to be placed in the turret center, one of the reasons why the main cannon is mounted off-center on the turret. Via an additional CCD camera the picture from this line can also be fed into the on-board computer network and displayed on all electronic displays within the vehicle. Besides that, the periscope offers an optronic thermal vision mode and a wide-angle camera with three zoom stages to assist the driver, as well as a laser range finder. The whole array is hunter-killer capable; the commander also has 5 vision blocks.
The gunner optics, which can be completely protected with a slide hatch, are mounted coaxially to the main gun. The gunner has a thermal vision camera and laser range finder (identical to those on the PERI) and an optronic day sight, rounded off with a vision- and a glass block. The driver has three of them, as well as an image intensifier and one display for optronic image feeds. Even the passenger cabin has a hatch and three vision blocks on the rear right side of the vehicle, one of them in a rotary mount. The rear cabin also has two electronic displays.
All in all, the Puma has an additional five external cameras at its rear in swing-mounts for protection while not in use. Apart from the glass optic periscope view directly accessible only by the commander and gunner (but indirectly via the CCD camera), all optronic picture feeds can be displayed on every electronic display within the vehicle. The provisions for the rear cabin enable the passengers to be more active than previously in assisting the vehicle crew either directly through the vision blocks and hatches, or by observing one or more optronic feeds. The whole crew has access to the onboard intercom.
Traditionally, IFVs are expected to interact with MBTs on the battlefield. In reality, many IFVs are not mobile enough to keep up the pace of an MBT. The Puma aims to close this gap with several key technologies. Firstly, its compact, lightweight MTU Diesel engine is unusually strong at 800 kW nominal output, which may make it the most powerful engine in use on an IFV today. Even at the 43 t maximum weight in protection class C, it has a higher kW/t ratio than the Leopard 2 MBT it is supposed to supplement.
The vehicle prototypes have a five-road wheel decoupled running gear and use a hydropneumatic suspension to improve cross-country performance while reducing crew and material stress by limiting vibrations and noise. The road wheels are asymmetrical, mounted closer to each other at the front. This is to counter the front-heavy balance, inevitable because of the heavy frontal armor as well as the engine and drive train which are also situated at the front. The 500mm-wide steel tracks made by Diehl are of new construction and lighter than previous designs.
The serial production vehicles will have a symmetrical arranged six road wheel running gear as shown on released pictures by the manufacturer.

- The German Army operates 5 Pumas for evaluation and ordered 405 more. On 11 July 2012, the order was reduced to 350, with production vehicles to be delivered in 2014.
Potential and future operators
The Department of National Defence is considering the purchase of vehicles meant to accompany the Leopard 2 into combat. The CV90, the Puma and the Véhicule blindé de combat d'infanterie are the most likely candidates for the role. A contract of 108, with an option for up to 30 more.
The United States Army sought a new family of vehicles to replace the aging fleet of M113 APCs and M2 Bradleys with the BCT Ground Combat Vehicle Program. With modification, the Puma satisfied the technical requirements of the BCT Ground Combat Vehicle Program and was offered by SAIC and Boeing. The SAIC-Boeing team was not awarded a technology development contract for their Puma-based vehicle in August 2011, and then filed a protest. The protest was denied in December 2011 based on concerns over the vehicle's force protection features, primarily the proposed active protection system and underbody armor, and 20 significant weaknesses which had potential solutions offered that were judged as inadequate. On 2 April 2013, the Congressional Budget Office released a report that advised purchasing current infantry fighting vehicles instead of developing a new vehicle for the GCV program. Buying the Puma would save $14.8 billion, and was called the most capable vehicle. The Army responded by saying no existing vehicle could match requirements to replace the Bradley.
