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 an 8×8 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 8×8 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.

Variants in service

[edit]

The following vehicles are in service, or in development to enter service.

Piranha IV 6×6 Korsak – "Spähfahrzeug Next Generation"

[edit]

The German Army is looking for a successor to the Fennek scout vehicle. GDELS Mowag offered a Piranha 6×6 variant at around 20 tonnes.[10] In October 2024, the Piranha was selected by the German Army, and the contract is expected to be signed in early 2025.[11]

  • Vehicle
    • Piranha IV 6×6 chassis
    • Amphibious capability
  • Weapon systems
  • Other systems
    • D-LBO digital information network of the Bundeswehr.
    • Mast sensor with:
      • optical and optronic observation systems
      • acoustic sensors
      • electromagnetic sensors

Mortar Carrier – "12 cm Mörser 16"

[edit]
12 cm Mörser 16

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

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 12 cm) and the 15,5 cm Festungskanone 93 (an artillery gun 155mm Caliber L/52).[12]

Sapper Vehicle – "PI PZ 21 (Pionier Panzerfahrzeug 21)"

[edit]
Pionier Panzerfahrzeug 21

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
    • Amphibious capacity
    • Crew: 1 driver, 1 commander, 2 sappers
  • Weapon system [13]
  • Sapper equipment [14] [15]
    • 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 [14]
    • Blade Manipulator Arm – provided by GCS [14] 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 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.[16]
  • 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.

Piranha IV 10×10 RCH-155 – "Artillerie Wirkplattform und Wirkmittel 2026"

[edit]
Piranha IV 10×10 RCH-155

Origin of the variant

[edit]

The programme "Artillerie Wirkplattform und Wirkmittel 2026"[17] is a Swiss Army project for a successor to its M109 Kawest tracked self-propelled howitzers.

In 2022, two systems were shortlisted for the programme:

  • A variant of the Archer Artillery System of BAE Systems Hägglunds, to be based on the RMMV HX2 8×8 chassis (the integration on a truck was being in development for the Swedish Army).
  • The KMW RCH 155 (Remote Controlled Howitzer 155) with two chassis options:
    • Boxer A3 (8×8)
    • Piranha IV 10×10 which at the time of the bid would have to be developed

GDELS Mowag collaborated with KMW to develop the Piranha variant. The advantage of this variant is to provide more space for the crew, more stability, and the capacity to shoot at full power at 360°.

In November 2024,, the Swiss Armed Forces selected the RCH-155 artillery system.[18] The Armed forces started to prepare the contracts for approval by the parliament, and to integrate the command and communication system into the platform.

Prototypes

[edit]
Piranha IV 8×8 StratCom – "Richtfunkpanzer"

Piranha IV 8×8 StratCom – "Richtfunkpanzer"

[edit]

The StratCom (Strategic Communication Systems) was presented by GDELS at Eurosatory 2024. It is equipped with a 15-meter communication mast system with point-to-point radio systems, and a C4I command system.[19] It is likely to become the successor of the Swiss Army "Radio Access Point Panzer".

Piranha IV 10×10 HMC – "Heavy Mission Carrier"

[edit]

The vehicle takes the chassis developed for the RCH-155 mounted variant, and can be fitted for various missions. GDELS announced this variant in April 2024. It is designed for a 17 tons payload, and a total weight of up to 40 tons. The axles 1, 2, 4 and 5 are steered. The turning circle is lower than 18 meters.[20]
