No. A ramjet relies on stagnation pressure at the inlet in order to compress air prior to combustion. They are typically not affectiveeffective until the speeds get quite high, somewhere in the Mach 2+ range.
Ramjet powered missiles which used rocket boosters for launch have been around for decades, possibly the most famous one is the US Navy’s TALOS missile. One of the most ambitious projects from the Cold War was a weapon called Supersonic Low Altitude Missile (SLAM). This would have used a nuclear powered ramjet engine and roamed the skies at supersonic speeds for months on end with a nuclear warhead, waiting for instructions to attack enemy targets.
