Quoting my1le (Thread starter): With the new 747-800 in production, what are the odds of seeing a new 747-8SP?
What would it be good for? The original SP was developed to overcome range issues in the original 747. Those issues are largely gone...especially once they reactivate the tail tank on the 747-8i, it's got enough range to do almost anything you could want to do. Put another way: who would buy it and why?

The same chance as Boeing restarting the 757 line, none. The 747SP was a niche a/c and as technology improved the range of a/c, there was less of a need for the 747SP. Boeing did propose a new 747SP called the 747 ASB that would have used the technologies used in the 747-400 but with a shortened fuselage similar to the 747SP. No airlines were interested in it, as it was a niche a/c like the 747SP.
In this day and age, there are plenty of twin engine a/c that can do the same roles as the 747SP and carry more passengers and cargo.

The SP only sold forty-five models, even airlines that could have really used it eg Japan Air Lines to fly New York to Japan nonstop, didn't buy it. Not a successful subtype, makes the current 747-8i look like a runaway success by comparison.
So who bought it? Iran Air to fly nonstop to NY and LA (LA never happened), Qantas to fly nonstop to California, Pan Am to fly nonstop to Sydney (although with the P&Ws as opposed to QF's RRs, it almost never made it without stopping in HNL) from LA and from New York to Bahrein and Riyadh, South African Airlines to fly around Africa in the days when they couldn't overfly the continent due to their government's racist policies, Saudia to fly nonstop to NY and Washington, Syrianair for the prestige of having a pair of 747s (they didn't need the range, the longest sector they ever flew was to LHR, five hours), one VIP machine to the Iraqi government and that's about it. Did Braniff buy new? Maybe they did. Then one or two others and of course some secondhand operators (Air Mauritius, Luxair, American, TWA, United, Corsair etc).
I flew Mandarin from Taipei to Sydney in 1994 and Iran Air CGN-CGN (enthusiasts' charter by Air Events) in 2004 and LHR-IKA on the very last bookable SP flight out of Heathrow in 2009 (the Iran Air schedule changed the next day to A300 and before it changed back, IR's 747s were banned from EU airspace). Wonderful aeroplane, the most exotic and interesting of all 747s.
Any other 747SP memories?
fly Saha Air 707s daily from Tehran's downtown Mehrabad to Mashhad, Kish Island and Ahwaz

What does the tail tank provide?
How would a 744 length aircraft with 748 wings/engines look? It would basically be the -SP of the current generation, but depending upon how the range/performance looks, airlines might buy...744 or even 742 sized aircraft with -8 engines and wings. Would this have better payload/range than a 772LR? Would economics permit, after hypothetical demand is met?
btw, what length of upper deck would be most efficient for a -400 sized shrink of the -8? What upper deck length is most efficient for the -8?

Weren´t the later versions of the 742 able to largely make up for the 747SP performance?
I flew it many times on AR´s MEX-LIM-EZE and MEX-EZE. Of course on LIM-EZE. It had a pretty sprightly take-off performance, specially when lifting off at MEX. Inside it felt a lot like being on a DC-10 rather than on a 747. When AR moved their F cabin upstairs, sometimes in the 80s the SP kept it in the nose. For me, who am a fan of the Premium services being on the nose of the 747 that was a neat feature. The 742 had a spiral staricase, while AR´s SP had a straight one, but I suppose that was merely a result of the fact that it was built to Braniff´s specification.
I also recall circling over EZE when arriving on the Southern winter months in the wee hours of the morning and EZE being closed due to fog. Other times we would have gone straight into MVD if flying on the 742, but the SP just circled around when EZE opened which was usually by 08AM.
It was a neat plane to be aboard, but I always preferred the 742.

It still is a niche aircraft, albeit with a very, very limited niche (given that plenty of A and B twins can do the same thing as Sutter's Balloon, in terms of range and payload). Four engines and a large fuselage, along with rock-bottom purchase prices make it good choice for scientific research and engineering applications:
Iran Air and Sands use the type because of the economic embargo, and they are still cheaper to fly than a -200 series, when there is a light load (and sometimes over long, thin routes, the aircraft's original intention):
An extra 3300 gal of fuel. Good for about another 400-500 nm.

What would they buy it for that the -8 can't already do?

The chances of another 747SP is effectively zero. Remember, the original 747SP--which used the same engines as the 747-100--only had a range of 6,600 nautical miles, still less than the 777-200ER with is 7,200 nm range but similar pax/cargo capacity. Even fitted with modern engines, a 747SP would probably have a range of (probably) 7,400 nm, which is still less than what you get with the 777-300ER with its 7,800 nm range.
My favorite aircraft ever built, it's sexy looking, and had limited success. If I had offensive amounts of money, my first acquisition would be a 74L, refurbish to my liking and needs, then roam the world. I have taken pictures of every one I have ever seen at airports worldwide. My favorite liveries were, BN, SA, QF, TW were some of the best. Sigh, things change.

AIRLINERS.NET CREW FORUM MODERATOR
When I read the thread title, my first thought was "yea, its called the 77L/A345." The 747SP was a plane when long range was 6,650nm. That is a range now met by a large number of widebodies (A332, 788, 77E/77L/77W, 744/748i, A380, MD-11, A343/5/6, and at this hour I'm probably forgetting one or two). Heck, the 763ER almost has the 747SP range now!
And look at the 77L, due to its lower passenger volume, its desirability is far less than the 77W.
The range to not require a shrink. As already noted, 400 to 500nm more range.
If someone wants a big (non-777 or 787) to go long haul, they would want the A380R or a high MTOW 748i. Anyone who wants the cost per flight of a 748i will demand the payload. Otherwise, they could buy a 788 in two years and fly any route a 748SP could do.

Actually,QF ordered the -SP for flighte to Wllington,NZ. I never read about QF's -SP'S having trouble on LAX-SYD,it was PA's with the P&W JT9D's that had troubles.

Flew the Pan Am SP from LAX to SYD and on to MEL great aircraft to ride in and I guess at the time it was a great leap as far as long haul across the Pacific went, intead of the LAX/HNL/Nandie/SYD/MEL multable stops it was one stop LAX/SYD/MEL. Great looking aircraft. The chances of the SP making a come back are as good as Aeroflot bringing back an IL62 for their long haul flights ZERO!

one of the above photos is the NASA SOFIA flying telescope. That airplane is an EX Pan-American SP-21 and the former United 147UA Nose 8647 acquired with the Pan-AM Pacific Division in 1986.

Arguably, the 747SP of today is the 777-200LR. Both are niche aircraft that fulfill a very limited and very similar market need. Both were/are extremely capable under the standards of their day, which means the 777-200LR is way more capable than a 747SP; and it only needs two engines to do it.
