Picture this.
Exclaiming "Alarm" from the watch deck is the crew's signal to get the boat under as quickly as possible or we are all dead. period.
So there you are standing on the watch deck and you see the sunlight glint on the canopy of a Mosquito bomber rolling over in a split S maneuver to dive in and fire it's wing mounted HVAR rockets into your sub.
ONE HVAR rocket is enough to seriously criple your submarine to the point that it either cannot dive at all, or it dives uncontrollably.
Seeing this sunlight glare overhead you and your crew now have about 25 seconds to complete the following
1. Relay the ahead flank order to the engine room
2. Set the stern planes to maximum dive angle
3. Set the bow planes to maximum dive angle
4. Open the main tank vents to full open
5. secure all compartments
6. ready the electric motors
7. all non-essential personnell must run at full tilt for the forward most compartment to put all dead weight in the front of the U-boat to pull the bow down into the water as quickly as possible.
8. Clear all 5 or 6 men from the watch tower
9. close and lock the water tight watch tower hatch
by the time you have completed all of these tasks you have managed to submerge to about 10 meters depth
now your forward momentum is slowed, reducing the dive speed as the diesel motors stop. now is the time to engage the electric motors and shove them to flank speed to compelte the dive process to 70 meters as quickly as possible.
by now the mosquito bomber pilot closing in on you at over 200 knots has launched all 6 of his HVAR rockets at your submarine which he can still clearly see beneath the water at it's current depth.
you have literally only a few seconds remaining to escape disaster.
as you clear 25 meters, the ocean above you is blasted into a frenzy of explosions as your boat rocks violently, the lights fuse and the interior of the u-boat falls completely dark.
Men scramble to re-fuse the lights in pitch black as the beam of flashlights scan the command room passing through showers of salt spray.
with a few minor repairs your boat will be fit for combat again.
you have escaped death by a very narrow margin.
all because a young saior peaked his head down the hatch and exclaimed
ALLAAAAAAAAARRRRRRMMMMMM!!!!!!
