Nexter Trajan 155 mm/52 caliber towed gun

The Trajan is a 155mm 52 caliber towed gun artillery system designed and manufactured by the French Company Nexter Systems. The Trajan TRAJAN is an accurate and powerful 155mm caliber towed gun system able to support any mechanized and armored unit. The TRAJAN system can be put into action in less than 1’30”. The gun is served by a six-man crew and is very much facilitated by automation of operations for putting it into or taking it out of action, for aiming and by an automatic loading of shells. These elements also make operations more secure. To design its new Trajan towed gun, Nexter Systems relied heavily on the combat proven, truck-mounted Caesar, which is performing superbly in Afghanistan from the FOB held by the French army. In September 2011, Nexter Systems of France and Larsen & Toubro Limited (L&T) of India signed an Agreement announcing the formation of Nexter Systems led consortium for 155 mm Towed Gun Artillery program for the Indian Army. Under the proposal, Nexter will field TRAJAN, 155 mm/52-calibre weapon system. TRAJAN offers enhanced firepower through quicker response, longer range and improved accuracy. Larsen & Toubro, in association with Nexter Systems, will manufacture critical subsystems for TRAJAN which will integrate and provide required support for the gun system to the Indian Army. Nexter and L&T are teaming for the Towed Gun System programme of the Indian ministry of defence, by proposing the TRAJAN which has already been evaluated in India. The French Company iXblue is also a partner in the Trajan programme with its ADVANS VEGA Intertial Guidance System (also present on 105 LG and CAESAR systems). It enables the gun a high degree of precision in autonomous firing. In February 2016, Nexter submitted its final bid in an Indian tender for a €1 billion ($1.1 billion) contract for 1,400 155mm towed cannons. Nexter has teamed with Indian partner Larsen & Toubro to pitch its Trajan 155mm/52 caliber gun against Elbit Systems, partnered with Bharat Forge. The Trajan has a total weight of 13,000 kg and can be easily transported by military transport aircraft as IL-76, C17 or A400M.
The Trajan towed gun is based on the CAESAR 155mm / 52 caliber gun into a modern towed gun system fitted with a firing control system, automated implementation such as in/out of action, laying and ammunition handling and loading in order the crew can performed sustained firings with limited efforts. The Trajan has a range from 4.5 km to 42 km with an ERFB ( Extended Range Full Bore) and even 55 km through the use of rocket-assisted projectile (VLAP Velocity-enhanced Long-range Artillery Projectile). It can be also used in direct firing with a maximum range of 2 km thanks to day and night sight devices. The TRAJAN firing rate is six rounds per minute and can fire 45 rounds in 30 minutes in case of sustained firing. It has an elevation range from -2º up to +73º, and traverse range of 34º. The lower part of the Trajan will be designed by L&T under the supervision of Nexter, who will retain authority over the design of Trajan. This carriage will be inspired by the French-made TRF1 155/39 calibre gun.
Ammunition
The Trajan 155mm / 52 caliber gun is fully compatible with all 155mm 39 / 52 caliber NATO standard ammunition (Joint Ballistic MoU), and can fire ERFB shells and smart ammunition (BONUS, SPACIDO…).
Mobility
The TRAJAN 155mm towed gun is equipped with an auxiliary power unit that provides it with all the energy necessary for electrical and fluid equipment, and can travel at 10 km/h under its own power to reach its firing position. When towed, its tractor can travel at up to 80 km/h with no constraints, and can turn on turning diameters of 25 m. In towed configuration, TRAJAN can be remotely controlled from the truck cabin. The front part of the cradle is equipped with two wheels and two trails at the rear with one small wheel located at the end of each trail.
Acessories
The TRAJAN 155mm towed gun reaches a high level of accuracy by integrating a muzzle velocity radar (MVR), an inertial navigation unit (INU) and a ballistic computer. TRAJAN has been designed to reach a high efficiency in all fire actions such as direct support fire, in-depth action fire, counter-battery fire. A shell handling crane is available as an option.
TRAJAN 155 mm/52 caliber towed gun of French Nexter Systems is being offered to India to meet the country’s army TGS (Towed Gun System) towed howitzer program.
TRAJAN weapon system feature a auxiliary power unit, inertial navigation system, muzzle velocity radar, hydraulically operated automatic loading and aiming system, embedded fire control system able to be connected to field management system.
It has a rate of fire of 6 rounds per minute and a range of 42 km using base bleed-base bleed extended range full bore (BB/ERFB) shells and more than 55 km using rocket assisted ammunition.
TRAJAN has a combat weight of 14 tons, elevation range from -2º up to +73º, and traverse range of 34º.
An 80 hp auxiliary power unit and hydraulic transmission are available to provide the howitzer with self-propelled capability with a road speed of 10 km/h and off-road speed of 5 km/h. In towed configuration, TRAJAN can be remotely controlled from the truck cabin.
