Continuity mistake: During the attack a parked US plane is blown up and the prop goes cartwheeling off along the runway. Not wishing to waste a perfectly good explosion the director filmed this from several different angles and used the same explosion several times. You can easily see the prop each time.
Continuity mistake: When the USS Ward first spots the mini-sub trying to sneak into the harbor, we see a close up of the conning tower. The forward edge of the conning tower is undamaged. Next we see the USS Ward fire it's first shot and we see the shot miss and hit the water well forward of the mini-sub. Look at the conning tower and there is now a square notch in the forward edge. The USS Ward fires its second shot. Just before the special effects explosion you can see the forward edge of the conning tower is undamaged. After the flash from the shell hit on the conning tower subsides, we can now see the square notch which we saw after the first shot which missed. Finally, the mini sub submerges and in the underwater shot, the forward edge of the conning tower is again undamaged.
Continuity mistake: When the sub is trying to sneak into the harbor, the first shot shows it with the conning tower out of the water, when the U.S.S. Ward spots it, all they see is the periscope, but when they start to shoot at it, the conning tower is once again out of the water.
