notes"The Archer Artillery System, or Archer - FH77BW L52, or Artillerisystem 08 is an international project aimed at developing a next-generation self-propelled gun system for Sweden and Norway. The heart of the system is a fully automated 155 mm/L52 gun howitzer and an M151 Protector remote-controlled weapon station mounted on a modified 6×6 chassis of the Volvo A30D, all-terrain articulated hauler. The crew and engine compartment is armored and the cab is fitted with bullet and fragmentation-resistant windows. Aside from this, the system consists of an ammunition resupply vehicle, a support vehicle, BONUS and the M982 Excalibur guided projectile. The project began its life in 1995 as earlier studies for a self-propelled system based on the FH 77. Further test systems received the designation FH 77BD and FH 77BW. By 2004, two prototypes had been ordered based on a lengthened version of the FH 77B mounted on a modified Volvo Construction Equipment A30D articulated haul truck (6x6). In 2008, Sweden ordered the first batch of seven units, while Norway ordered one. In August 2009, Norway and Sweden ordered 24 Archers each, in a cooperative deal. The Howitzer was developed for the Swedish armed forces following a contract awarded to Bofors (now BAE Systems Bofors) in 2003 by Försvarets Materielverk (FMV), the Swedish defense acquisition agency to build two demonstrator howitzers. The prototype FH77 BW L52 self-propelled howitzers entered firing trials in Sweden in 2005 and 2006. In September 2006, the FMV placed a contract for detailed design work on Archer and, in January 2007, a contract for the next development phase. The Swedish Army has a requirement for 24 systems (two battalions). Following In September 2008, the Swedish government approved the final development and procurement of the Archer artillery system. In November 2008, Sweden and Norway signed a cooperative agreement for the development of the Archer system and, in January 2009, awarded BAE Systems a contract to complete the development of the artillery system with the exception of the remote weapon system which is made by Kongsberg Defence & Aerospace. A final prototype is scheduled for completion by September 2009, which is expected to be followed by a contract for 48 systems – 24 for Sweden and 24 for Norway. Archer was planned to enter service in 2011 but was delayed until October 2013. This is because of unforeseen technical problems. The Swedish Army received its first four pre-serial productions FH-77 BW L52 Archer systems on 23 September 2013, and the first guns finally entered service on 1 February 2016. The Norwegian government withdrew from the project in December 2013. The vehicle platform is a modification of the Volvo A30D 6×6 articulated all-terrain hauler vehicle. The vehicle cabin and engine compartment are fully armored and the cab is fitted with bullet and fragmentation-proof windows. The cabin seats up to four personnel. The howitzer is operated by three or four crew. The system also includes a munition carrier consisting of a removable, modified standard container mounted on a ballistic-proofed all-terrain lorry. The unit cost is approximately $4,500,000."

value"The vehicle carries 21 x 155mm projectiles in the fully automatic magazine. Reloading the magazine from the accompanying munitions carrier takes about 10 minutes using the purpose-built lifting device. The howitzer can use NATO modular charges or Bofors Uniflex 2 modular charges. The Uniflex 2IM modular charge system consists of two sizes of combustible charge cases; one full-size and one half-size case, both filled with the same type of insensitive guanylurea dinitramide [fr] (GuDN) propellant. The modular charge system allows several increments of charge to be available and increases the gun system's multiple rounds simultaneous impact (MRSI) capability and good range overlap between the increments. With BAE Bofors/Nexter Bonus rounds the range is 35 km. The range of the gun is extended to 60 km with the precision-guided Raytheon/Bofors XM982 Excalibur round. The Excalibur shell is corrected in flight towards a pre-programmed trajectory by a GPS guidance system. For armoured vehicles, the Bofors 155 Bonus is used."
