Dreadnought Approaching

“Captain! Martian dreadnought approaching! Camera four!”
Captain Davis pulled into his chair and fastened the tethers that would hold him there if the ship had to make any sudden maneuvers. “Faction identification?”
“No beacon sir. Still waiting on a report from Optics, but no visible markings.”
“Crap.” Davis switched his console to the number four camera and a silvery dot appeared on his screen against the emptiness of space. “How long until it gets within range?”
“Six minutes.”
“And the Portsmouth? How far out is it?”
“Eight minutes.”
Davis swore. He had allowed their escort to go too far from them. They’d be sure to regret not having the cruiser and its guns if the dreadnaught came within firing range. “Get ready to hail them. All frequencies.” He turned to his left and selected a prerecorded message in eleven martian dialects, all demanding to know the dreadnaught’s intentions.
Davis resolved not to wait for the radio waves to go across the space between them and back. “Put the ship on alert, and call back the Portsmouth. Are the spitfires fueled?”
“Almost. Forty-two are reported ready, twenty-two still in progress. Autocannons are all loaded.”
Davis nodded to himself. Had the dreadnought appeared earlier during their test flights they would have been defenseless. “Launch all of our fighters.”
The alert aircraft took off immediately, becoming blips on the ship’s radar screen. Davis was relieved to see his untested crew working without hiccups as they readied the other spitfires for launch.
Meanwhile, the minutes ticked by with no response from the dreadnought. Davis hoped that theirs was a chance encounter, but he knew the odds of that. The space around them was completely devoid of anything of value. That was why they had picked it. It was a place to test Earth’s new carrier away from prying eyes.
“Two minutes.”
Still no response from the dreadnought. “And the Portsmouth?”
“Four minutes.”
Davis looked back to view of the dreadnought on his console. It was now close enough for him to begin to make out more details of its design. Like most martian ships it resembled a slab of iron with an engine strapped to one end. On its hull was an assortment of weapons clusters, sensor arrays, and docked support craft that looked like off-color pixels on his display.
Davis knew that in a one-on-one fight the carrier would be outgunned by the dreadnought. Their ship was designed to carry and support fighters, not exchange broadsides. He also knew that many of their spitfires would be lost to martian point defense canons. Space combat was still new to humans, while martians had over a century experience. His pilots would be turning theory into practice as they went. It was going to get a lot of them killed.
“One minute.”
Davis glanced at the blips on the radar screen. All of them were waiting for his orders. If he hesitated any longer the dreadnought would be on top of them.
