Patria ARVE
The Patria ARVE is a self-propelled howitzer that is based on the Patria 155 GH 52 APU field gun and the SISU E13TP all terrain 8×8 truck.
Development
An initial digital designed was made public in 2015. One of the mentioned objective with this project was to ensure a domestic capacity to produce howitzers.In 2017, Finland selected the K9 Thunder as its new self-propelled howitzer, and the project became dormant. But following the 2022 Russian invasian of Ukraine, needs to quickly modernise the indirect fire capabilities arose. Among the systems that need to be replaced are the field guns, especially the old soviet guns. The results of the Nexter CAESAR in the Ukraine war confirmed that this type of systems would be a good solution to replace the field guns, an economical and effective system, complementary to the K9 Thunder.
In 2024, the development of the project by Patria advanced with the intent to make a prototype. The first prototype was unveiled in 2025 at Arctic Event 2025, and its name was unveiled, the Patria ARVE.
In June 2025, Patria announced having fired the system for the first time. And the performances were as expected, even with a maximum of charges.
Design
Prototype
The prototype takes the existing Patria 155 GH 52 APU gun, and is installed on the chassis of the SISU E13TP with an added hydraulic stabiliser installed at the rear of the vehicle. The spade is lowered before firing to transfer most of the recoil into the ground.Gun
The gun barrel is equipped with a single-chamber muzzle brake.Ammunition
The system can transport 24 complete ammunition.Capabilities
The prototype can shoot its first round 90 seconds after stopping, and it is ready to leave 45 seconds after the last round is shot. The firing rate of the system is:- 3 rounds in the first 15 seconds
- 8 rounds per minute at its maximum rate of fire
- 2 rounds per minute at a sustained rate
