The most efecctive technique for getting a missile through a targets defenses is not supersonic or subsonic it is suprise!. Exposing a launch platform in this fashion can increase risk and defeat the potential for tactical suprise. This places onus on the launch platform to develop the track and hold it long enough for the launch sequence to complete. Historically, therefore, supersonics have had to be fairly tightly locked in before launch. The inherent problem with that is that it simultaneously reduces the available window of opportunity for the missiles seeker to do all the things it needs to do. 31st August 2009 at 01:55 - Edited 1st January 1970 at 01:00Ī supersonic attempts to defeat countermeasures by minimising its exposure window through the targets defensive-systems envelope. Subsonics also tend to be smaller, allowing more to be carried by a shooter. If the subsonic is stealthy, the time between its detection and target impact is small, limiting the ability of defensive measures. OTOH, subsonics can be programmed to follow circuitous routes to the target, making a multi-axis simultaneous saturation attack easy to accomplish. Large size also limits the number of super/hypers that can be carried by a shooter. Super/hypersonics tend to be large because of the large quantity of fuel needed to loft them. High speed also makes them stand out for doppler and severely limits maneuverability (pretty much a straight line to the target). Super/hypersonics are hot IR targets that can be detected at great distance. "Engage" involves surviving the target's defenses and final maneuvers to hit the required spot on the target. I would give the advantage to subsonics because super/hypersonics cannot carry sensors with sufficient range to assure timely terminal maneuvers or sensor mode changes to reject countermeasures. "Track" involves sensor capability and the ability to discriminate target features while rejecting countermeasures. Track-engage are missile tasks that I believe are easier for subsonics to accomplish than super/hypersonics for the following reasons: Pk requires all links in the kill chain - find, fix, target, track, engage, assess.įind-fix-target-track-assess is simpler to implement on the shooter rather than the missile, so missile speed probably isn't a big discriminator for these tasks. Oh, and you can't let your wife/kid use it without being in violation of the NFA unless you have it owned by a trust where the family memebers are trustees.- 31st August 2009 at 01:19 - Edited 1st January 1970 at 01:00īy "efficient" do you mean the highest probability of kill? 22 suppressor there is something like $40NZ, here you're looking at $4-600, a $200 tax stamp, and a 6month wait for the BATFE to do a background check that the FBI does in less than a week. I really wish that there was no NFA and we could buy suppressors like some countries (New Zealand comes to mind). I personally have fired rather large rifles without ear protection, and its generally not real pleasant. You can generally avoid most ear protection shooting suppressed, even with supersonic ammo (you won't be in the shockwave so no need to worry about it). And it does make shooting much more pleasant. Of these bits of the gunshot, only 1) can be addressed with a suppressor. Imagine dropping a large boneless beef roast on a tile floor from a few meters up. A rifle bullet impacting flesh is a very loud slap. This is louder than you'd expect.Ĥ) the bullet's impact - very much louder than you'd expect. Can be avoided by using subsonic cartridges/loadings.ģ) the weapons action - at the very least the firing pin's impact on the primer. These would most likely get you subsonic velocities.Īnother thing to consider when shooting a pistol vs a rifle and comparing sound signatures is that a pistol will eject more unburnt powder into the air around the muzzle as its had less barrel length to burn said powder.Īs far as suppression goes, there are four main components of the sound signature of a gunshot:ġ) muzzle blast - the expansion of deflagrating powder in the atmosphere as it exits the barrel.Ģ) sonic crack - the bullet creating a shockwave through the air. Now, you could use one of the other rimfire variations (.22 Short. A pistol (assuming a 6" bbl) is really close to supersonic, if not a bit over. 22 Long Rifle is generally loaded supersonic from the test fixtures, even in the standard loadings.
