Russo-Ukrainian War: Artillerisystem 08 Archer 155mm SPH

Source: General Staff of the Armed Forces of Ukraine

     One of the more unique artillery systems in use by Ukrainian Army artillery units is shown here, the Artillerisystem 08. Better known simply as the Archer, this vehicle is in service with one of the four artillery battalions of the 43rd. Artillery Regiment “Hetman Taras Triasylo”. Sweden, as part of the country's military aid to Ukraine, has provided 8 Archer systems and in September 2025, pledged another 18 systems. Of the eight, one was damaged by a Russian drone attack on March 3, 2024 with a second destroyed on August 4, 2025. Designed by the Swedish company Bofors between 1995 and 2009, the Archer entered production in 2010, being built by BAE Systems AB. To date, only 48 Archer systems have rolled off the line with over twice that on purchase orders from the Latvian Land Forces, Swedish Army, and Ukrainian Army.

     The basis of the 34-ton Archer is the Volvo A30D articulated 6x6 vehicle chassis which is used in the civilian construction industry (usually as a dump truck). Power comes from a Volvo D9BACE3 inline-6, intercooled diesel engine with a turbocharger that develops 340 horsepower. This is mated to a Volvo PT1560 automatic planetary transmission with a 8-speed gearbox (6 forward, 2 reverse). Three Volvo AH64 axles feature transversal differential locks with full floating axle shafts. The driver can select 6x4 or 6x6 drive on the fly. The maximum road speed is 43 miles per hour while the top reverse speed is 8 miles per hour. 105 gallons of diesel fuel provide for a maximum operational range of 400 miles.

     Situated on the very back of the chassis is the heart of the Archer, a turret mounted Fälthaubits 77 (FH77) L/52 155mm howitzer. The turret is able to traverse a total of 170 degrees and elevate the gun to a maximum of 70 degrees. Total depression is 1 degree. Housed within the turret is a fully automatic gun loading system and electronic fuze setter. Total onboard ammunition is 21 shells with a total of 126 modular propellant charges. The shells have their own magazine while the propellant charges are in a separate magazine of 18 rows which contain 6 full charges and 1 half-charge. Once all of the ammunition is expended, it takes the crew 10 minutes to reload assuming they have the Archer-specific reloading device that moves ammunition from the accompanying munitions carrier into the magazines.

     The turret itself is unmanned and instead, the gunner operates it from the cab. A FCS (Fire Control System) utilizing NABK (NATO Armament Ballistic Kernel) software generates ballistic tables for any ammunition being used along with both tabular and graphical firing tables. The FCS also automates bringing the howitzer onto target, positioning the turret without manual guidance. This is assisted by a SAGEM Sigma 30 inertial navigation system (INS). The howitzer has several fire modes to include burst fire (3 rounds every 20 seconds), sustained fire (54 rounds every 35 minutes), bombardment (21 rounds in 3 minutes), and MRSI (Multiple Rounds Simultaneous Impact). With MRSI, the FCS calculates the trajectory then handles the firing of 4 to 6 rounds so that all rounds impact on the target at the same time. The Archer is compatible with any NATO standard 155mm projectile with standard HE (High-Explosive) shells having a range of around 19 miles, extended range HE shells reaching out to 25 miles, and M982 Excalibur guided shells can attain a range of 31 miles. If need be, the Archer can engage in direct fire, out to a range of 1.2 miles. Shell speed upon exiting the barrel is measured by a Weibel MVRS-700SC muzzle velocity radar. From the halt, the Archer can be ready to fire in under 30 seconds. Stability during fire missions is provided by two rear-mounted stabilizers. Likewise, the Archer can be ready to move to a new position, also in under 30 seconds.

     For local defense, a Vapenstation 01 RCWS (Remote Controlled Weapon Station) can be fitted to the cab roof. The Vapenstation 01 is the Swedish designation for the M151 Protector RCWS which can be fitted either with a Browning M2 12.7mm heavy machine-gun or a Mk.19 40mm automatic grenade launcher (among other weapon fits). While the Vapenstation 01 is not seen in the photograph, there are some Ukrainian Archers which use it.

     The Archer's cab (holding the 4 man crew) is protected by STANAG 4569 Level 3 steel armor which provides proof against 7.62x51mm AP (Armor-Piercing) ammunition at 30 meters as well as 155mm shell fragments from 60 meters. Below the cab, the Archer supports STANAG 4569 Level 2b mine protection which permits the Archer to survive the blast from a mine packed with at most 13 pounds of explosive. Air filters and a crew cab overpressure system provides NBC defense (Nuclear, Biological, Chemical). In the photograph, the Archer is covered by a Saab Barracuda MCS (Mobile Camouflage System) which consists of fitted panels which is a multi-spectral camouflage. It features a high UV reflectance, patterns that match NIR (Near IR) reflections of the surrounding environment, SWIR (Short-Wave IR) management by adjusting spectral reflections of the environment, TIR (Thermal IR) reduction (utilizing convection, reflection, radiation, and insulation), as well as providing protection against SAR (Synthetic Aperture Radar) systems.
