The use of a liquid-propellant rocket engine in the Sarmat intercontinental ballistic missile (ICBM) can be considered an outdated solution. This was stated by the American publication TWZ.
The publication's analysts noted that liquid fuel technology is a relic of the Cold War.
Liquid-fueled missiles are difficult to keep fueled for extended periods.
Nevertheless, the liquid-propellant rocket engine surpasses its counterparts in power, TWZ added. Such missiles also have a weight advantage compared to solid-propellant ones.
Russia successfully tested the Sarmat missile. It can fly 35 thousand km, and none of the existing air defense systems are capable of shooting it down. The ballistic complex will enter service with the Russian Armed Forces in 2027.
