I really don't have much to go on for this, good luck
Back in the 90s or early 2000s I remember catching a few scenes of a movie or TV show that was playing in the background while I was over a relatives house. I feel like it was probably from about that time period, at the oldest it was maybe from the 80s, and absolutely no newer than about 2004.
The main thing I remember was that at some point it cut to a scene of a cruise missile flying at low altitude over the ocean, and I feel like it might have done that several times
There may have been 2 missiles, I remember them being white, and kind of a rectangular shape (the real life AGM-86 ACLM is pretty close to what I remember the shape being)
I feel like the plot was that there was some kind of a race against time to do something before the missile hit its target and that it cut to scenes of the missile flying a few times, but again I wasn't paying much attention to it and it's mostly just the scenes of the missiles flying that stuck in my head.
I really got nothing else. I feel like my best bet to identify it is if you can show me a scene with the missiles because that's really the thing that has for some reason stuck in my mind since I was a kid.
EDIT: after spending some time googling different missiles, probably getting myself on some kind of watchlist, some other kind of similar-looking missiles to what I remember
SOM
AGM-154
AGM-181 LRSO
Storm Shadow
Apache
Taurus KEPD 350
Wan Chien
That sort of square/rectangular shape of the missile is kind of what stuck out to me as a kid and made the image stick in my brain, I thought they looked cool
The scenes with the missiles flying I'm pretty sure were in the daytime
There may have also been a scene with them being launched from a plane, which tracks because most or all of those I listed seem to be aircraft-launched
It was also definitely a live action movie/show
The race against time aspect may not be correct. I was only half paying attention and probably saw less than 5 minutes of this movie in total.
EDIT2: Never say Never Again is probably the closest answer I've seen so far. Not totally sure that's it, but it gives you a pretty good general idea of what I'm remembering
