The evolution of the smart gun
The prototype, in development since 2009 through the Soldier Integrated Precision Effects Systems (SIPES) project, includes a firing mechanism to shoot lightweight cased telescoped ammunition, a secondary effects module for increased firepower and a NATO standard power and data rail to integrate accessories like electro-optical sights and position sensors.
In order to support the multi-role nature of the weapon, the prototype’s secondary effects module features the ability to install either a three round 40 mm grenade launcher, or a 12-gauge shotgun. When optimized, the integrated weapon prototype could weigh less than a C7 equipped with a M203 grenade launcher, reducing the burden on soldiers.
The development of the weapon prototype posed a considerable challenge. DRDC scientists analyzed advanced material technologies that could replace the metal used in heavy components. The lightweight case telescoped ammunition was tested extensively with the support of the Munitions Experimental Test Centre in Valcartier, Quebec to assess its long-term aging behaviour.
Scientists also studied how to increase the rifle’s accuracy using technology that can automatically detect targets and assist with engaging them. Questions related to the sensors needed to accurately geo-locate targets for target data sharing were also investigated.
How the soldier interacts with the weapon was also the subject of numerous human factor trials. Ergonomic and weapon prototype handling tests were performed by Human Systems Inc., under the supervision of DRDC scientists, with CAF soldiers from military bases in Petawawa and Edmonton. The testing was crucial to developing optimal design criteria to meet the CAF’s needs for the Small Arms Modernization project.
“DRDC expertise provides the CAF with solid scientific data so they can make more informed decisions for their major acquisition projects.”
“The results of the first phase of the project have shown that DRDC expertise can be used to provide the Canadian Armed Forces with solid scientific data so they can make more informed decisions for their major acquisition projects,” said Dr. Guy Vézina, the Director General for S&T Army, DRDC.
The new weapon prototype is a promising development for the soldier of the future. The integration of electronic components will allow soldiers to generate or receive data from the command and control network. In the next phase of development, automated target detection and assisted target engagement will be the subject of an in-depth study in the Future Small Arms Research (FSAR) project.
Finally, the development of the integrated weapon prototype and the continuing analysis of promising technologies should facilitate the acquisition of the next generation of small arms by the CAF. The data collected and the analyses documented so far by DRDC scientists will be used in conjunction with the data and analyses that will be generated in the FSAR project to develop the technical criteria that will form part of the statement of operational requirement documentation for the CAF Small Arms Modernization project.
