CH-124 Sea King Historical Thread

I love that title. Keep my eyes open for that book.
Probably contact the Shearwater Aviation Museum to see if they still have copies for sale. I think only 1000 (maybe 500?) were printed for the 2018 Sea King Retirement.

The Shearwater Aviation Museum has other Sea King related books for sale, though.

If I rmember I'll check the next time I'm in.

John and I were chatting about the research I've been doing as late as last week.

There’s six at museum shop. I talked to the curator, Christine, and she’ll take orders over the phone. Since we’re closed it will have to her cell phone; pm me if you want her number.

Here are pictures of all the books that are for sale:

The irony of how the tactical fit of the Sea King evolved is that even though a navigator was employed (the RN model), much of the capacity for command and control from that was eaten up by operating the equipment (which does not require an officer), so little capacity remained for command and control (which does).

Additionally, as time went on, the USN model evolved to remove much of the burden of operation by adding a dedicated helicopter link (eventually including a robust Link-16), better autotrackers, and better tools, so that the 60R actually has a decent capacity to operate independantly even though it doesn't have a dedicated tactician (except in Australian et al service, where the second pilot is replaced by a nav). Ironically, meanwhile in the Cyclone the nav (ACSO) is still overcoming limitations in the radar auto-tracker and plot compilation.

This is what I meant by feeds into the current discussion in these forums. Hypothetically, if the Cyclone was to be replaced by the 60R (something I don't support, I think we should put the money that was missing in the first place to solve the problems, even if Sikorsky can't be convinced and we find somebody else, say IMP), who will occupy the left seat, a tactical pilot or a nav?

I lean towards a pilot; it allows the USN training system to be used, and allows robust OJT for the pilot's. Junior pilots fly with seniour ones, and middlings fly together.

This also raises another question. Would it be better to offload the track and link management functions to a second AESOP in the Cyclone (it is a NCM function in the ship), remove sensor operation from the non-flying pilot (except possibly EO/IR as an extension of their Mk-1 eyeball and put in place better tools for that), and have the non-flying (pilot not in control) be the tactician, with an optimized toolset? Ie, no ACSO. This would give the master apprentice model in the back as well, and possibly streamline training?

Which raises another question; was the opportunity missed in the Sea King to explore this as the technology evolved?
 
So, a hypothetic...

It's 1993,the old ASN-501 is still in the aircraft, the CH-124B HELTAS is just coming online, we actually understood that the Persian Gulf wasn't a one off and that doing less ASW is a reality for the next 25 years, and we also understand there is less money for the next 10 or so.

Instead of just saying "I'll take my pen, and write zero 'elicopters" Cretien says "I've directed that the EH-101 be cancelled, as it is not the right helicopter for Canada at this time. Furthermore, DND is to investigate the proper fit for the future. To that end, we will fund appropriate investments in the Sea King to keep it flying for 10-15 years and update it to understand what the true requirement is."

Project office rapidly (as if) gets to work, and determines that the ASN-150 is the best choice because:
  • already fielded in the 60B
  • can have more than one workstation (60B had one in the back for a second aircrewman and one in the front for a "co-tac," the non-flying pilot)
  • future proof by having a 1553 bus
  • can display video and a tacplot
  • has the 123 tacplot link, but not Hawk Link

In order to implement that, they put in place Canadian software support and the following:
  • radar scan converter to put the radar picture and the tacplot together (thereby enabling the British model of having the Observer [ie Nav] handle radar and plot)
  • keep the sonar wet end but use the HELTAS UYS-503 processor the display it (giving both dipping and sono processing, but not many buoys)
  • put the FLIR on the display
  • three workstations; two in the back, and one for the left seat pilot
  • a method of receiving and transmitting on the Link is installed in the ships, which includes forwarding from / to Link-11.

So, now you could follow either model. The overlaid model would let you keep the nav, do better command and control, and use the front end for SA and task offload. The data link would allow you to do the USN model of a co-tac, and depend on the ship/fleet for higher level C2.

You're crewing options are therefore:
  • two pilots, two navs (the EH-101 model), with the sensors being run by a nav due to the influence of the CP-140 on MH crewing choices
  • two pilots, one nav, one AESOP (the Sea King, Cyclone, and RN model)
  • two pilots, two AESOPs (the 60B model, with less C2 capability)
  • one pilot, one nav, two AESOPs (a plused up RAN model)

Which model do you choose ("controlled by the ship" enabled by the link, or independant), and which crewing?

I know my choice, but I'm interested in the discussion (if anybody cares)...
 
In 1993, without as much digital battle space capability as there is in today’s MIoT, I’d stick with 2 PLT, 1 NAV, 1 AESOP to get the ‘BSM’ function, but to fight the system, would even consider a 1 PLT, 2 NAV, 1 AESOP option depending on the use of then automation and open mindedness on the part of the operator/pilot mafia.
