Mowag Piranha IV
The Piranha IV is the fourth generation of the Piranha family of armoured vehicles by MOWAG GmbH. Its development started in the 2000s as a fully private venture. A first prototype was unveiled in 2001, and a second in 2004.[3] This new version offered an increased volume inside the cabin, and a higher level of protection.

As the Piranha IV was being developed, the ownership of MOWAG changed. It was acquired by General Dynamics in 2004 to become part of General Dynamics European Land Systems.[4]
History Edit
Following the previous version of the Piranha (Piranha III) and its derivatives (LAV III, Stryker), a need for a larger and better protected vehicle arose from the international weapons market.
The solution offered by Mowag was a 8x8 with an internal volume of 12 m3 (420 cu ft) (compared to the 11 m3 of the Piranha IIIC). Vehicle weight was 25 t (25 long tons; 28 short tons) (18.5 t for the Piranha IIIC). Despite this weight increase, the mobility of the vehicle was improved thanks to a new suspension design and a more powerful engine.[5]
This new generation of the Piranha family triggered the interest of foreign manufacturers. A licence for its production was acquired by Alvis Vickers (which became BAE Systems Platforms & Services) with the intention to manufacture the Piranha IV in the UK and in South Africa.[6] Another licence was acquired by Komatsu which was looking for a 8x8 platform for the "Future Wheeled Combat Vehicle" (Shorai Sorin Sento Sharyo) of the Japanese Ground Self-Defence Force. In the end, neither company manufactured the Piranha IV; the Japanese army selected the Type 16 for the role, and there was never a proper interest by the UK.[citation needed]
In 2007, the UK launched the Future Rapid Effect System (FRES) competition for a heavy multi-role armoured vehicle after cancelling participation in the Boxer collaboration. The British Armed Forces were looking for a much higher protection level than was possible with the Piranha IV. GDELS Mowag therefore presented a new generation of the Piranha family in 2007, the "Piranha Evolution".[7] It was selected for FRES, along with the Boxer and the VBCI for FRES Utility Variant (UV) trials and the Piranha V with General Dynamics UK was chosen as the preferred bidder to develop the Piranha into a vehicle to meet British requirements but the UV requirement was dropped due to budget cuts and the decision reversed.[8] Despite losing the program, GDELS-Mowag developed this variant further into the 33-tonne Piranha V. GDELS-Mowag is able to offer 8x8 armoured vehicles in several weight categories including competing in the heavy category against the Boxer]], the VBCI, the Patria AMV, and the Freccia IFV. This enabled the sale of the Piranha V to Denmark, Spain, Romania and Monaco.[citation needed]
Design Edit
One of the main differences with the former Piranha vehicles is the protection level.
- Front armour protection against armoured piercing (AP) ammunition of 20 mm and 23 mm calibre.[9]
- All-around armour protection against 14.5 mm AP ammunition
- All-around armour add-on available to protect against 20 mm/23 mm AP (meeting STANAG 4569 protection level 5
- Floor protection against anti-tank mines and Improvised explosive devices (10 kg TNT equivalent)
Variants in service Edit
Mortar Carrier – "12 cm Mörser 16" Edit
This weapon system was developed for the Swiss Armed Forces, by GDELS Mowag and RUAG. Some of the main elements of its design are:
- Vehicle
- Piranha IV chassis and running gear
- Roof opening
- Space for up to 30 rounds
- Crew: 1 driver, 1 commander, 2 loaders
- Weapon systems
- 120 mm RUAG Cobra automated mortar system connected to the "Integrated Artillery Command and Fire Control System" 97/14 - INTAFF TA
- Protector RWS equipped with a 12.7 mm M2 Browning machine gun
Origin of the variant Edit
The Swiss Army expressed the need for a more mobile heavy mortar system, and evaluated a need for 4 batteries to fulfil its mission. The need for a heavy mortar system arose after the Swiss Government decided to stop using the, "lm fort 12 cm 59/86" (fortress twin-mine launcher 12cm) and the 15,5 cm Festungskanone 93 (an artillery gun 155mm Caliber L/52).[10]
Sapper Vehicle – "PI PZ 21 (Pionier Panzerfahrzeug 21)" Edit
This sapper vehicle was developed for the Swiss Armed Forces, by GDELS Mowag and various subcontractors for the tools.
Some of the main elements of its design are:
- Vehicle
- Standard Piranha IV chassis and running gear
- Crew: 1 driver, 1 commander, 2 sappers
- Weapon system [11]
- Protector RWS equipped with a 12.7mm M2 Browning machine gun
- Sapper equipment [12] [13]
- Quick Coupler Adapter (QCA) – provided by Global Clearance Solutions (GCS) System that enables to change rapidly the tools / attachments depending on the missiona
- Mine plough – provided by Pearson Engineering Ltd A mine plough designed to clear the mines laid in surface
- Combat Bulldozer Blade – provided by GCS [12]
- Blade Manipulator Arm – provided by GCS [12] A remote manipulator arm used to manipulate in order to identify and treat explosive threats
- 2 light spots in the front
- Cameras for the technician and the drive
Origin of the variant Edit
As part of the Armament Program 2021, this vehicle was designed to replace the replace the fleet of Minenräumpanzer – M113 63/00 , a demining armoured vehicle. In the Swiss Army, the M113 63/00 is not the only sapper vehicle in service. Since 2008, the Kodiak (Leopard 2) was introduced, its mission being to support a heavy assault to breach minefields, trenches, and ditches.
The Swiss Army needed therefore a Sapper System complementary to the Kodiak. Moreover, the urbanisation of Switzerland having increased implied that some additional capabilities were needed on top of the demining mission and it would have to be modular to exploit the investment to the fullest.
- The choice for a wheeled platform was justified by a need for a more mobile army.[14]
- The blade was selected to enable the army to open a path where it would be needed (pushing obstacles on a road, covering a trench line, etc)
- The manipulator arm was a need defined from the return on experience of the NATO countries in Afghanistan and Iraq that were the target of an important number of IED attacks. It enables to perform ordnance disposal from a well-protected vehicle.
Prototypes Edit
Piranha IV 10x10 Artillery Gun Module – "Artillerie Wirkplattform und Wirkmittel 2026" Edit
Project Artillerie Wirkplattform und Wirkmittel 2026[15] was a Swiss Army project for a successor to its M109 Kawest tracked self-propelled howitzers. In 2022, two systems were shortlisted. The first was the BAE Systems Hägglunds Archer Artillery System to use the RMMV HX2 8x8 chassis (the integration on a truck is in development), the second was the German Remote Controlled Howitzer 155 (RCH 155) on either the Boxer or Piranha IV platform. The Boxer was already developed, and in trials at the time but the Piranha IV would have to be integrated with the gun system. To that end GDELS Mowag and Krauss-Maffei Wegmann started to collaborate on a variant of the RCH-155. In May 2023, the first models of the prototype in development were revealed; the gun system would be installed on a Piranha IV 10x10 platform. This would provide the crew with more space compared to the Boxer based variant; this meant the whole artillery crew could be within the vehicle rather than operate some parts of the system remotely.

Komatsu proposed the Piranha IV for the Future Wheeled Combat Vehicle Program (Shorai Sorin Sento Sharyo). The competition was lost against the Type 16 Manoeuvre Combat Vehicle (Hitoroku shiki kidō sentōsha) developed by Mitsubishi Heavy Industries.[16] - Polish Army In 2002, Poland selected the future multi-role vehicle intended to replace the OT-64 SKOT, the BMP-1, some command vehicles, mortar carriers and some armoured engineering vehicles. The competitor for this contract were the Piranha IV, the Pandur 2 (8×8) and the Patria AMV. This last one won the competition, and has been manufactured in Poland under the name KTO Rosomak. [17]
- Royal Netherlands Army
RDM Technology received a licence from Mowag to manufacture the Piranha IV for the Dutch Army. RDM offered the Piranha as a competitor to the Boxer in 2000 as a replacement option of the M577 and the YPR-765.[18]
