The Sikorsky S-61

This beautiful ship was designed from the Sikorsky SH-3 “Sea King”. Back in the late 50s Sikorsky won a development contract for an amphibious anti-submarine warfare (ASW) helicopter capable of detecting and attacking submarines. Which turned into the SH-3, from there Sikorsky developed a commercial version, the S-61, which first flew on 2 November 1961, and was 4 ft 3 in (1.30 m) longer than the SH-3. The S-61 had a greater pay load to carry both freight and passengers, initially the production S-61Ls were powered by two 1350shp GE CT58-140 turboshafts, the civil version of the T58. The S-61L features a modified landing gear without float stabilizers.
Los Angeles Airway was the first to start operating the S-61L as a passenger helicopter on 11 March 1962, Just a random fact, when LA Airways bought them, they were priced for 650,000$ today the US is selling them for 500,000$ which can be found here at the GSA Auctions. PIA began operating the S-61s in 1962, The helicopter route to Khulna reduced the 21-hour journey overland to 37 minutes by air. 20 towns and cities covered by the network. The average price of a ticket was 25 rupees (which is about 2$ today)

On 7 August 1962, the S-61N made its first flight. Otherwise identical to the S-61L, this version is optimized for over-water operations, particularly oil rig support, by retaining the SH-3’s floats. Both the S-61L and S-61N were subsequently updated to Mk II standard with improvements including more powerful CT58-110 engines giving better hot and high performance, vibration damping and other detail refinements.

The latest version is the modernized S-61T helicopter. The United States Department of State has signed a purchase agreement for up to 110 modernized S-61T aircraft for passenger and cargo transport missions in support of its worldwide operations. The first two modernized S-61 aircraft will support missions for the U.S. Embassy in Afghanistan.

Variants of the S-61

Over the years the S-61 has been operated by a lot of different operators, here is a list that I could find.

Why do I think we need the S-61?

The S-61 has a huge impact in commercial passenger service through out the history. Flying people from Airport to Airport, delivering mail, VIPS, I think this historical helicopter would be a great fit. Virtual Airlines like British Airways, AF-KLM group could open new doors and a new way to fly. The several other operations the S-61 did this allows new styles of Virtual Airlines, everything from Search and Rescue, to Off Site operations, not only does this work in the civilian market, this also works in the Virtual Military market, it allows Virtual Militarizes like the Global Air Force, United States Air Force Virtual to allow new way of transporting their crews and staff.

I hope this is a start of an interest to people wanting a new style of flying!

No. IF isn’t a helicopter simulator. X-plane has that. This would be far to complicated to implement considering its on a mobile platform


#3

IF is a Flight Sim, so… Helicopters Fly…

I don’t think so since Laura has said she’s tested helicopters in the past and it’s worked. To add on if X planes mobile has a S-76, how is it to complicated for another Mobile app?


#4

Infinite Flight Is a Flight simulator meaning anything that can fly can be added and it’s not just about planes can also be helicopters mate it’s literally called Infinite Flight


#5

They added in a space shuttle before…


#6

I do agree with this statement. i saw it on Live stream. but my concern is, trolling around the surroundings of an airports. Flying or blocking the Runways and imagine those other scenarious. i think there will be some rules about this.


#7

We see it with other aircraft too, training and casual server is a good place to see these things take place at.


#8

old boiiii! Honestly IF will be another level better with Helicopters


#9

I freed up a vote for a heli. It’s time. A training helicopter would be nice too. Gotta start somewhere…


#10

Personally I’d like see this before a R22, in real life those who fly an R22 can fly anything but they’re so touchy lol


#11

Beautiful definitely freeing up a vote for a helicopter


#12

Thanks for your vote!!


#13

Completely agree with the need to have some rotary wing aircraft added. Are they a little more complex? They certainly are! Is the flight profile more complicated? Yes Sir! Is it worth it to add some helicopters? You better believe it! As a retired Apache aviator, I fully support this endeavor!!


#14

Warrant or Commissioned?


#15

Warrant. Retired as a CW2. Didn’t get through flight school until I had 12 years in.


#16

Best rank in the Military!


#17

Unfortunately Infinite Flight probably wouldn’t be adding helicopters anytime soon. That’s a nice chopper though.


#18

Rotorguy, you just need to invite the IF staff to come for a visit. That should seal the deal 😉


#19

You never know. They could.


#20

Ughhh. Please do not mention, the egg around here.
