707 Versions

[louross]

Is there a simple chart that gives the basic differences between the various versions, like wgts, PAX, range, etc?
thanks,
louross.

Well, I couldn't find a simple chart, but you'll find lots of info here:

Thanks for that- interesting site, but couldn't find the info I wanted.

Hi Louross

I think a simple chart probably doesn't exist

The same basic model flying for two airlines will probably differ in those sorts of figures depending on how it's set up.

Even aircraft in a fleet may vary as they may have some configured for fewer pax and longer range.

So I think it's a case of basic difference and the figures you want would have to be research for that particular aircraft.

I do a lot of internet research so if I do find anything I will post.

Whats the difference between the 707-320B and C?

Thanks,

Bill

Hi Bill,

I might be wrong on this but I believe "C" model is a cargo configuration or can be configured for cargo usage.

Thanks Ray, visually I see no difference, and I think engine wise there is not difference either. C for cargo might me correct.

I also seem to remember reading that the C model had stronger landing gear, and as a result is rated to take off and land at heavier weights.

I think the same is true of the 'F' model DC-8s.

Regards,

Jim

YEAH .... B707-320B & C are essentially the same. The "C" has higher operating weights .... hense the need for strengthened landing gear. Powerplant-wise there's a a bit of a mixture with some of both types using P&W JT3D-3B or P&W JT3D-7 series fanjet engines .... depending upon airline choice !

This might help you .... I just drafted it up

B707-120 (original short tail and no ventral fin).
P&W JT3C-6 turbojets .... possibly water injected but I'm not sure.
Fuselage length 144ft 6in. Wingspan 130ft.10in. MTOW 257,000 lb. Range 2,670 nm (no reserves)

B707-120B(tall tail with ventral fin added).
P&W JT3D-1 or JT3D-3 fanjets (often also referred to as turbofans) .... depending upon airline selection. Fuselage length 144ft 6in. Wingspan 130ft.10in. MTOW 257,000 lb. Range 3,680 nm (no rserves)

B707-138 (original short tail and no ventral fin).
P&W JT3C-6 turbojets .... with water injection. These aircraft were a shortened version of B707-120 (reduced by 10ft) designed especially for QANTAS Airways. Only the first 6 of these aircraft delivered to QANTAS (VH-EBA thru -EBG .... all 1959 deliveries) were short tailed and JT3C-6 turbojet powered. The remaining 6 138's delivered to QANTAS between 1961 and1964 (VH-EBH thru -EBM) were all tall tailed, ventral finned, and powered by P&W JT3D-3B fanjets and designated "B707-138B". All 6 original QANTAS 138's were then also converted to 138B's during the early 1960's. Fuselage length 134ft 6in. Wingspan 130ft.10in. MTOW 247,000 lb (later 257,000 lb). Range 4,080 nm (no reserves).

B707-220 (original short tail and no ventral fin).
P&W JT4-A3 turbojets .... this version was designed as a "HOT AND HIGH" aircraft for Braniff International. Only 5 were ever built and these also later featured what became the standard B707 tall tail with ventral fin. None of these aircraft were ever re-engined with fanjets/turbofans. Fuselage length 144ft 6in. Wingspan 130ft.10in. MTOW 247,000 lb. Range 2,670 nm (no reserves).

B707-320 P&W JT4A-3, JT4A-9, or JT4A-11 turbojets .... depending upon airline selection. This version featured an 8ft 5in fuselage stretch for what became the definitive B707 fuselage length of all subsequent B707 versions. A few ("very few") of the initial production versions of B707-320 entered service with the short tails (AIR FRANCE) and without the ventral fins but were later added to all. Fuselage length 152ft 11in. Wingspan 142ft.5in. MTOW 312,000 lb. Range 3,820 nm (no reserves)

B707-320B (tall tail with rear fuselage ventral fin).
P&W JT3D-3 or JT3D-3B fanjets .... depending upon airline selection. This version also featured increased wingspan. Fuselage length 152ft 11in. Wingspan 145ft.9in. MTOW 331,000 lb. Range 5,250 nm (no reserves)


B707-320C (tall tail). P&W JT3D-3, JT3D-3B, or JT3D-7 fanjets .... depending upon airline selection. Equipped with forward fuselage maindeck freight door. All were tall tailed but some aircraft never featured the rear fuselage ventral fin. Fuselage length 152ft 11in. Wingspan 145ft.9in. MTOW 333,600 lb. Range 5,000 nm (no reserves)

B707-420. RR CONWAY 508 fanjets.
Apart from its powerplant the -420 was otherwise identical to the -320. It was the first B707 version to fly wth the tall tail and ventral fin added which became standard features of "definitive B707 verions" (-320B/C). It was also the first 707 version to fly with fanjet engines. Again a few ("VERY VERY FEW") initial production versions of B707-420's entered service with short tails and without ventral fins (AIR INDIA) .... but again .... these "were" later added after the Braniff accident and British COA requirement. Fuselage length 152ft 11in. Wingspan 142ft.5in. MTOW 312,000 lb. Range 3,980 nm (no reserves)

B720 (sometimes also referred to as "B720-A").
P&W JT3C-7, or JT3C-12 turbojets .... depending upon airline selection. Tall tail and ventral fin equipped with 8ft.4in reduction in fuselage length from that of B707-120. Fuselage length 130ft 11in. Wingspan 130ft.10in.

B720-B P&W JT3D-1, or JT3D-3 fanjets (derated) .... depending upon airline selection. Tall tail and ventral fin equipped with 8ft.4in reduction in fuselage length from that of B707-120. Fuselage length 130ft 11in. Wingspan 130ft.10in.

These details are all quoted from the "GOSPEL ACCORDING TO MR BOEING".
