...Tomahawks, have you ever heard of GPS signal jamming? I don't need to shoot down any of them.
The Tomahawk does not require GPS.
GPS signals are for accuracy enhancements, but not for navigation. The Tomahawk cruise missile, as an active weapons platform, predate GPS, and was already lethal enough with just inertial navigation.
Please do not talk as if you know what you are talking about.
That's the last line of defense. Iraq used it on limited number of incoming missiles back in the Persian Gulf War and all of them missed their targets.
I want to see a credible source that says
ALL Tomahawk cruise missiles missed their targets due to GPS jamming.
However, Iran doesn't talk about it much. It also has cruise missiles with range of 2500 km called Sumar that can launch from both land and sea against both land and sea targets.
Let me guess, Iranian cruise missiles are perfect.
It is not a fair comparison. An ASBM approaches its target from above, thus it has direct visual of its target even from 30km away while a low flying cruise missile visual is limited to 16km due to curvature of earth's surface.
The guidance system of ASBM has enough time to calculate the path of its target and hit it. Also remember carriers can't do evasive maneuvers even against torpedoes and their top speed is negligible considering the limited time involved from the instant the ASBM locks to the point it hits.
You are
TECHNICALLY confused between 'guidance' and 'navigation'.
Regarding missiles, guidance is about staying on path. It has
NOTHING to do with the target. Take the basic ballistic missile as example. Its projected path is predetermined by factors such as airspeed, ballistic arc, and duration of engine burn. There are more but the basic three will suffice. During flight, it will be affected by environmental factors that unless corrected will take the missile away from its intended destination. Its inertial navigation will sense attitude changes and will send compensation commands to the flight control system. The same INS will guess that the missile returned to its originally intended path and stop those compensating commands.
Navigation is about looking at one's current position, where one intends to be next, and taking actions such as steering to get from A to B. In navigation algorithms, there are only two points of A and B. A map can have A to Z, but as far as the navigation computer goes, when it reached B, point B becomes A and point C becomes B, and the process continues until the final location is reached, and that final location is not Z but B. There is a 'master' map that will keep track of all points A to Z, but for the steering algorithm, it cares only from A to B.
The inertial navigation system (INS) computer would have programmed waypoints such as the coordinate of a mountain so that if the INS guess that it reached that waypoint, that waypoint becomes A and the next waypoint becomes B. The steering algorithm does not care if the waypoint is that mountain. It just need to know that it as a new starting point A and a new destination B. It is up to the INS computer to keep track of waypoints completed, from A to Z.
Nothing about the target comes into play.
It is the
SENSOR package that have information about the target.
Most do not know this bit is esoteric factoid of weapons targeting algorithm: a 'non-fixed' target is not the same as a 'mobile' or 'moving' target.
It all depends on if the weapon actually sees what the target is doing. A 'non-fixed' target is when the weapon did not see the target moved from one location to another. A 'mobile' target is when the weapon actually sees that displacement from one location to another. Each condition necessitate its own targeting algorithm to create that steering command that tells the missile here are waypoints A and B. It does not matter if the difference between A and B is one meter or one kilometer.
The greater the difference between A and B, the greater the steering command to change the missile's heading. If the weapon actually sees the target moving from A to B in smaller increments, such as a ten-meters or one-meter increment, the smaller the multiple steering commands. The greater the steering command, the greater the physical stresses on the weapon as it change to a new heading. Stress that could negatively affect its accuracy. This is why it is always good to have 'eyes on' target.
An anti-ship ballistic missile can be assumed to have a sensor package.
The guidance system of ASBM has enough time to calculate the path of its target and hit it.
The target can create an EM blanket that is electronically hundreds of km in square area. Same for infrared countermeasures.
In a ship vs missile scenario, if the missile failed by just one meter, the ship wins.
...I have passive radars that can detect when a F-22 starts its engine in their base in Emirates.
There is no such animal as a 'passive radar'.
Radar detection is a two-parts process: Transmission and Reception.
Transmission is active. Reception is passive.
If you chose to be passive, someone must be active. His transmissions would deflects off a target so you being passive could detect those reflections. But if no one actively transmits, then there will nothing to detect.
Technical ignorance results in flawed military tactical and even strategic errors.
