You said "laser beam" before. Now we can all see that that was wrong. Now, for some odd reason, you mention "infrared" doesn't refract. While I won't argue against that, you are wrong again -- the Sea Sparrow uses radar, not laser, and not infrared. This looks like your own mistake as I could not find the Navy instructor saying laser or infrared.
Conventional radar is subject to line of sight limitations -- that's why some planes can fly "under the radar" to avoid being detected. So conventional radar is typically only used from airplanes, or to track airplanes, not flying under the radar.
For longer range ship to ship, or surface to surface tracking, there are other "over the horizon" radar techniques to go beyond line of sight limitations. One is bouncing signals off the ionosphere. Another is using even lower X-band "longwave" frequencies that have the property of being able to follow the curvature of the earth. These "longwave" frequencies are especially effective over water, and especially effective at tracking ships at 50 nmi, albeit with less accuracy due to the lower frequencies and longer wavelengths.
Sea Sparrow missiles use a "semi active radar homing" technique for guidance, using the active radar signal from the ship, and passively detecting the radar echo off the target, and correcting its course continuously in flight -- this inherently overcomes and corrects for any Coriolis (and other) effects, whether up, down, left or right. This technique becomes more accurate as the missile gets closer to its target.
(Your nails in the coffin are made of straw).
Ships use planar geometry on flat maps (but not the flat earth map) -- the curvature of the earth is taken into account when projecting a curved surface onto a flat map. It is this distortion onto a flat map that enables the practical use of planar geometry.
Ship gyroscopes use local attitude disturbances as inputs to counter-act roll, and keep the down side of the ship pointing down (in the same direction as the downward force of gravity). They don't need to be aware of a globe earth -- they only need to be aware of which way is down.
The US Navy missile instructor is probably correct that he doesn't have to learn, or teach, or correct for Coriolis or globe earth -- it's already done for him in the software algorithms that drives his displays, and the feedback algorithms that guide missiles. Scientists and mathemeticians have already done the corrections so Navy personnel don't have to. It's not checkmate -- you missed a couple moves. You don't win wars with Navy personnel doing calculations in combat.
Your flat earth arguments are falling flat.

* Typically it is an 8 missile launcher from a ship
* Ship uses gyroscopes to stabilize & works on flat/planar geometry only
* Fire control paints a 2 inch beam via direct line of site at a target from a ship
* This 2 inch beam is not bounced off the atmosphere, again it is direct line of sight
* Target reflects the signal
* Targets are tracked up to 50 nautical miles away (1 nautical mile = 1.15078 miles)
* Infrared devices don't lie and do not refract- if you see the object, it's there. Mirages do not show up. Another nail in the globe coffin.
* No curvature of earth nor Coriolis effect taken into account
* According to the globe curve table (see reference section) a 50 nautical mile target would fall 2,207 ft (8" x 57.539 x 57.539) /12"
* The globe model completely falls apart here- direct line of sight only
The military has no training program for the curvature of the Earth. This is all you need for flat Earth. Checkmate. You do not win wars with false and inaccurate telemetry.
I will take the word of any active service US Navy missile expert over your ignorant statements. Go to the 35 min - 39 min mark for an exact description of how the 2 inch beam is used to paint the target The US Navy active duty veteran explains the process.
In addition, he talks about search radars tracking up to 200 miles away Go to 40-41 min mark.
