BAE Systems Land UK is developing a new 155 mm extended range (ER) high-explosive (HE) projectile to meet potential home and export market requirements.
The 155 mm ER HE projectile features a screw on base bleed (BB) unit that leverages from the company’s development and production of the 4.5 inch HE projectile for the Royal Navy, and could enter production in 30 months.
According to the company, the initial 155 mm ER HE projectile will have a range of more than 40 km when fired from a 155 mm/52 calibre ordnance or over 30 km when fired from a 155 mm/39 calibre ordnance as currently fitted to the BAE Systems Land UK AS90 self-propelled (SP) artillery system and 155 mm M777 lightweight towed howitzer.
The new 155 mm ER HE projectile is compatible with the BAE Systems Rokar Silver Bullet precision guidance kit (PGK) and fuze, which has already undergone extensive tests and demonstrated a circular error probable (CEP) under 20 m.
The PGK features hardened electronics and GPS guidance and features two pairs of canards that are used to stabilise and steer the 155 mm ER HE projectile in flight. Guidance commands are enabled via a radio frequency link.
Prior to firing, the user can select the multifunction fuze (MFF), which can be set for height of burst (HOB), delay, time, or impact.
The projectile will have a RTA (RDX TNT Type A) or Insensitive Munition IMX-104 HE payload, which weighs approximately 10 kg.
It is expected that first firings of the baseline projectile will take place at the Eskmeals range in Cumbria within 2018, using an AS90 system with a 155 mm/39 calibre barrel.
