Orange orbs appeared and hovered off coast before moving towards beach, then they abruptly accelerated and extinguished their light

I was on the balcony of my North Myrtle Beach SC oceanfront hotel room observing the constellation Orion in the northeastern sky when I saw 4 distinct orange orbs/spheres aligned within a haze/aura or opaque/cloudy background of a larger figure appear over the ocean. They eased through the sky and seemed to be approaching the beach when they quickly accelerated and darted to my left and their light was abruptly extinguished. A few minutes later, they abruptly appeared again over the ocean where they hovered then they seemed again to stream towards the beach before abruptly accelerating and turning and their light again was extinguished. Additionally, there was no sound emitted from the vehicle.
 I spent ten years in the Navy working in the special intelligence and cryptology communities (Naval Security Group/NSA) and I also spent 3 years at sea on an aircraft carrier, so I am very familiar with military aircraft and Navy ships/vessels. On another note, a week earlier from the same balcony, I saw and captured a poor image of a submarine on the surface near the horizon with what appeared to be a sub-tender and fishing trawler equipped with antenna array.
