Final answer:
The question addresses the maximum effective range of the SMAW with an HEAA rocket, involving principles of projectile motion in physics. Without air resistance, maximum range is at a 45° angle, but this decreases slightly when air resistance is considered. The effective air defense perimeter for stationary SAM sites is typically around 30 nautical miles, not directly correlated with the range of a portable weapon like the SMAW.
Step-by-step explanation:
The question pertains to the maximum effective range of the Shoulder-launched Multipurpose Assault Weapon (SMAW) equipped with a High Explosive Anti-Armor (HEAA) rocket. In physics, when analyzing projectile motion without air resistance, the range is maximum at a 45° launch angle. However, when air resistance is factored in, the optimal angle for maximum range decreases slightly below 45°. Additionally, there are two launch angles that add up to 90° which yield the same range. While this is true for theoretical calculations, actual effective range must also consider additional factors like the target's characteristics and operational conditions.
I do not have the specific range data for the SMAW with an HEAA rocket, but for general air defense, an effective air defense perimeter is estimated to be within a radius of 30 nautical miles for confirmed SAM sites. It's crucial to note that this is just an estimated effective range for stationary air defense systems, and the specific range for a portable weapon system like the SMAW could be substantially different and should be obtained from reliable military specifications data.
