Canada bets on cat-sized missile to solve costly drone defence dilemma

A lightweight missile developed by Calgary-based North Vector Dynamics could illustrate a broader shift in modern air defence, where the challenge is no longer intercepting sophisticated aircraft but stopping waves of inexpensive drones without exhausting costly missile stockpiles. According to an analysis by Defence Blog, the company's new CM-70 counter-drone interceptor reflects both changing battlefield realities and Canada's push to strengthen its domestic defence industry.

A precision-guided missile weighing just 3 kilograms is emerging as one of Canada's latest contributions to the rapidly evolving counter-drone market, with Defence Blog arguing that the system reflects a growing emphasis on affordable, domestically developed air defence capabilities.

North Vector Dynamics unveiled the CM-70 on July 27, describing it as more than simply another interceptor. The Calgary-based defence technology company presented the missile as evidence of Canada's ability to design, manufacture and control advanced weapons systems domestically, reducing reliance on foreign suppliers at a time when Ottawa is placing greater emphasis on strengthening its national defence industrial base.

The CM-70 is designed specifically to counter unmanned aerial systems (UAS), addressing a problem that has become increasingly prominent in conflicts such as the war in Ukraine, where low-cost drones are often used in large numbers to overwhelm air defences.

According to specifications released by the company, the missile measures 0.9 metres in length, has a range of 3.5 kilometres, and can reach speeds of up to 900 kilometres per hour. Defence Blog noted that earlier company materials and independent defence reporting, including from Janes, described a slightly lighter version capable of exceeding 1,000 kilometres per hour, suggesting the design has continued to evolve during development.

A defining feature of the CM-70 is its semi-active laser guidance system. Rather than relying on GPS navigation or radio communications, the missile tracks targets illuminated by a laser designator, allowing it to operate in GPS-denied and communications-denied environments where electronic warfare systems routinely jam navigation signals or intercept radio transmissions.

According to Defence Blog, this capability reflects the changing nature of modern warfare, where electronic warfare has become a standard feature of the battlefield rather than an exception.

The analysis also highlights the growing economic challenge facing air defence forces. Traditional interceptors used by systems such as Patriot can cost millions of dollars each, while many attack drones cost only a fraction of that amount. North Vector Dynamics has positioned the CM-70 as a lower-cost solution capable of engaging Group I through Group III drone threats, reducing the cost imbalance that defenders increasingly face.

The company says the missile can be launched from ground installations, vehicles or airborne platforms, enabling it to protect frontline positions as well as critical infrastructure such as power substations and water treatment facilities.

The concept has already attracted international backing. In May 2026, Czech defence manufacturer Czechoslovak Group invested in North Vector Dynamics through its Tech Horizons venture fund.

Fund representatives said affordable, multi-layered air defence against Iranian-designed Shahed drones and Russian-produced Geran variants remains an unresolved challenge, one the CM-70 is intended to address.

North Vector Dynamics has also received support from Canada's Department of National Defence alongside private investment. Led by chief executive Paul Ziadé, a former University of Calgary engineering professor, the company has emphasised that the CM-70 is ITAR-free, meaning it is not subject to U.S. International Traffic in Arms Regulations.
