“That’s phenomenal!”
“Yeah it is, but the best is yet to come. Here’s the kicker — literally, since it will kick you in the pants — we have the equivalent of an afterburner.”
“An afterburner?” Pappy asked incredulously.
“Yes. It works because of two engineerin’ features we have put together, ingeniously if I do say so myself. The first, we “borrowed” from the Russians. You’ve probably heard of the Shkvall?”
“Of course. Every submariner knows about the Shkvall or “squall” in English. It’s an underwater, solid-rocket propelled torpedo the Russians developed back in the late 1990s. The solidrocket motor can propel the torpedo at about two hundred knots partly because the torpedo reduces its drag by showering itself in a sheet of supercavitating air bubbles. If I remember correctly, the weapon produces a high-pressure stream of bubbles from its nose and skin that coats the torpedo in a thin layer of gas, greatly reducing the drag.”
“That’s exactly right.”
“But surely these fighters aren’t rocket powered, are they?”
“No. I said we borrowed somethin’ from the Russians, but it wasn’t the rocket — we have our own solution for propulsion — we borrowed the bubbles. During normal cruisin’, the bubbles are off, and the internal electric drive unit in the fighter can silently propel the fighter up to fifty knots or so, as you just saw. When the pilot kicks in the afterburner, two things happen. First, high-pressure air is forced out of hundreds of little holes along the leadin’ edge of the hull and over the surface of the wings, creatin’ the same sort of supercavitatin’ envelope used by the Shkvall. Second, our SQID-drive is activated.”
“Squid drive? What the hell is that?”
“The fighter has a water chamber that fills when the SQID drive is activated. When an extra boost is required, a hydraulically driven piston forces the water out of a nozzle on the stern at such high pressure and speed that the fighter is accelerated in a matter of seconds to — get this — over 150 knots!”
“What?” exclaimed Pappy!
“That’s right — it’s fully tested—150 knots submerged. Ready to try it?”
“I guess so. I don’t have much choice do I?”
“Nope.” Dwight slowed the fighter to about ten knots and then hit the SQID drive. After a short delay as the water chamber filled, the force of about 1.2 Gs pressed the two men to the backs of their seats. About seven seconds later, the speedometer indicated 150 knots.
“Wow, that’s incredible! But did we stay level? I would have sworn the nose pitched up when you hit that afterburner.”
“No, we stayed level the whole time. Your inner ear makes you think the nose pitched up. You see, the force pushin’ you back in your seat is almost equal to the normal force of gravity. It affects the fluid in your inner ear, and your brain says, “Hey, the only way I can experience this fluid motion is for me to be rotatin’ to a position where I’m looking straight up.” The inner ear and the brain were designed for 1 G — walking around on the ground. We fool them a lot with modern technology!”
“That’s cool, but why do you call it a squid drive?”
“That’s S-Q-I-D. It stands for Super-cavitation Quantified Injection Drive. It’s actually based on the way a squid accelerates. The squid has an internal bladder, which holds water, and when he needs to accelerate in a hurry he expels a water jet which accelerates him in the opposite direction. In our fighter, the power is simply unbelievable. You can roll one of these things into an angle of bank, hit the SQID activator, pull back on the stick, and pull four Gs underwater making a 180-degree turn. Now, you’re gonna make a lot of noise doing that because the SQID is pretty noisy and essentially the entire wing is cavitatin’, but who cares? You can outrun any torpedo shot at you, except for a Shkvall, and you can outturn anything, including the Shkvall. And unlike a rocket, which runs out of fuel, we use water! The water jet only lasts for about seven seconds, but as soon as the piston resets and the reservoir refills with water, you’re ready to hit it again!”
“Fantastic! I guess the limiting factor is battery power, right?”
“That’s right, but with our modern batteries, you should be able to cruise around for six to eight hours with no problem. Ready to try it yourself?”
“Absolutely!”
The men switched positions, and Pappy ran the fighter through its full range of capabilities. It was truly an incredible machine — quite a testament to George and Dwight’s engineering capabilities.
“Okay, Pappy, head us back west toward Platform Alpha, and I’ll show you some of our sonar capabilities. We have a little noisemaker attached to the recovery net. I’m searchin’ for it now and have a contact at two-eight-zero degrees. We have both active and passive sonar capabilities, but since we don’t want anyone to know we’re out here, we’ll just use passive sonar today. Let’s do some S-turns on our way in so we can measure different bearings to the target. We’ve installed a simple triangulation program, which continuously calculates and updates the range to the target. I’m showin’ the target at about twenty-seven thousand yards.”
“That’s a long way.”
“Hey, in this thing we’ll be there in no time.”
And they were. When they got within one thousand yards, they leveled off at a depth of ten feet and turned on the landing light to illuminate the area in front of the fighter.
“The net is stretched out in a north-south orientation,” said Dwight, “and the noisemaker is mounted in the center of the net. We’ll hit it on a westerly headin’, so all we have to do is keep the noisemaker centered dead ahead, and we should fly right into the center of the net.”
About one hundred feet out, the net came into view, and Dwight was exactly right — they flew right into the center of the net. The deck crew immediately hoisted the fighter out of the water and set it on the deck of Platform Alpha. The net was removed, and the hoist was reattached to the fighter so it could be raised and set back on its dolly. After completing their shutdown checklist, Pappy and Dwight exited the fighter and headed back to Dwight’s office for a debriefing with George.
As they entered, George asked, “How did you like it?”
“Wow! That was the most incredible ride of my life!” Pappy exclaimed. “But I’ve been thinking about it, and I think I’m missing something. Tell me again, Captain, how do you intend to use these fighters? Without a recovery net, it seems like every mission would be a suicide mission because when that dude stops, he’s headed straight for the bottom!”
“All right,” said George. “I can explain, but it’ll take one more comparison first.”
“Okay.”
“We’ve compared traditional submarines to aircraft and concluded they’re like dirigibles, right? As far as their maneuverability is concerned, they suck. Sub-fighters are more like fighter jets. Their maneuverability is great.”
“Boy, I’ll say!”
“Now let’s compare traditional submarines, namely attack boats, to surface ships. Submarines are big, lumbering behemoths with tremendous firepower. We employ them against other big, lumbering behemoths, and we shoot it out with huge, long-range torpedoes like Mark 48s. What does that remind you of, Mister World War One?”
“Nothing,” replied Pappy, obviously tiring of the captain’s guessing games.
“All right, you’re giving up on me now so I’ll just tell you—battleships!”
