General Quarters! General Quarters! All hands man your battle stations! Air Attack!
Trotting (you couldn’t really run) pulling on his dungaree shirt, making his way down the passageway to the plant. Thud-booom … the 5” guns were starting up, God already? How close were those planes?
Down into the plant do a quick turnover with the junior watchstander and he scrambles off to his battlestation. Take an assessment of his watchstation … the Boiler fronts, He is now responsible for keeping the fires lit and steam pouring out to the main turbines , and the ships turbine generators for electrical power.
Check the stack periscope… still burning clean… the trick will be keeping a clear stack while changing burner sizes and forced draft blower speeds.
5” guns keep up a steady bass riff, the turbines whining out their one note song. Then the 40mm quad mounts open up like a snare drum.
They are close.
The deck shifts hard to starboard, the engine order telegraph rings out Back Full from ahead full… CRAP! things just went sideways… The basic version of what happens is a highly efficient high speed steam turbine has just been reversed into a much less efficient “backing engine”
“Torpedoes in the water!”… hence the breaks and turn …
The abrupt change from ahead to astern caused a dynamic change in temperatures and pressures in the steam system. The deaerating feed tank, hit with a slug of hot condensate and lower Aux steam pressure … Reached that point that all the water feeding the main feed booster pumps flashed to steam. Loss of feed!
The Main feed pumps tripped on low pressure, they had seconds …
Secure the Burners, stop the fire, without water the boiler tubes will melt, if water is returned to a hot empty boiler it’s a bomb …
Machinist Mates scramble to get feed restored, Pumps up, Pressure, slow, slow … His boilers are down, 20mm AA is now ripping out its staccato sound.
He might have heard the torpedoes whirr by but he was busy.
Engine order telegraph rings up “ahead flank” … Steam pressure is dropping fast.
Quick, like a bunny, pull a heavy burner out and grab a light spray starter nozzle…Slide in, lock in place, one quick look into the bullseye on the boiler and sees the back wall refractory is still glowing red … maybe … He slams open the fuel valve and the atomized fuel oil hits the hot refractory “THROOOM!” and blooms into a beautiful yellow flame. He’d just saved the time of a full lightoff procedure.
Cut in burner after burner, Pressure coming up nicely … Hard roll to port, speed up, Still calling Flank.
Pull the starter nozzle and start replacing “full” nozzles with “med” nozzles. Pressure good steady state steaming … except for the AA gunfire and crazy turns. He watches the color of the fire, temps. &press, and the smokestack periscope, to adjust combustion to optimal… at least until the load on the plant changed.
The .50 cals are firing now, they’re so close.
You can hear and “feel” bombs hitting farther away at other targeted ships. Our AA is firing nonstop, it’s even hard to pick out individual 5” gun shots, the noise is constant, a ripple of percussion. Hard to starboard! Deck tilting, Engine order telegraph rings “all stop” Quick! shutoff 2 burners and throttle back on the forced draft blower.
The two Med. Nozzles he just secured he replaced with full spray nozzles because he knew it was coming… He thought he heard high speed screws but wasn’t sure … “clang, clang” Ahead Flank!”
He cut in the full nozzles and watched his pressure. Down… steady… slow rise, swap a med for a full, crank up the blower, and ready the mediums again. Back to pressure … KRUMP! Shudder. Somewhere forward we got hit … Calls over the all stations of damage reports.
Hard starboard roll, AA never slowing down, “What was going on up there?!?”
He makes his way to the much needed coffee pot, fills his chipped and stained mug, takes a beautiful deep sip … and BOOOM shudder … another hit. Scan the boilers all’s well, another sip.
Chief comes by, they exchange basic info, (neither knows much of what’s going on) Chief wanders off to a watchstation that might need a little help.
Orders go out to start #11 turbine driven fire pump, we hardly ever run her, this might be serious.
The rumor mill kicks in, all sorts of terrible calamities were befalling us … boarded by IJN marines, IJN battleships in gun range, 4 IJN carriers attacking with all planes. The last one was the most plausible as our AA fire was insane.
The .50’s and 20’s slowed and stopped. We’re ahead flank no maneuvering. I shout out to the lower level watch to start the eductor and let’s get every bit of water out of the bilge … good for him he had started that right after we restored feed.
The 20mm AA started up again, another hard starboard, there go the .50’s … Close concussions and shockwaves. Lights flicker then go out. Battle lanterns are turned on. Duty Electricians swarm the switchgear readying a return of power. Adjust the burners and blowers for the sudden loss of load and get ready to bring the turbine generators up.
MM’s reset the turbine generators bring them up to speed and the electricians parallel the generator to the rest of the electrical system, online …
Slow roll to port, still Flank, Still every caliber AA gun is firing. Thuds, crumps, and thuds were heard and felt all over, from near misses to farther targets.
BOOM … shudder … we just took another hit.
Cut out a burner, watch the pressure … Cut the burner back in. Still slow rolling to port, still firing every AA gun. .50’s stop … 20’s stop …
Rudder midships, drop to ahead full. 40mm stop. 5” gunfire slows to a final ,spiteful twin burst … then the guns are silent. The plant is humming along nicely … Secure from General Quarters! Ahead standard … The junior watchstander returns and resumes his watch, The “senior” (by what 2 years?) goes back to berthing and crawls into his rack. He wrings the sweat out of his socks, and tries to find his cleanest dry t-shirt. He has a 6 hour watch coming up two hours from now.
