Image seems to show core alight at launch

The article states:

"The Titan IV was made up of two large Solid-fuel rocket boosters and a two stage liquid-fueled core. It was launched using the solid-fuel boosters alone, with the first liquid core stage ignited about 2 minutes into flight."

Looking at the image of the launch, it seems very much like the core engine is burning as well as the boosters. How come? europrobe (talk) 14:00, 5 April 2008 (UTC)[reply]

"Boosters"

The solids on the Titan IV were not boosters, they were the first stage. Boosters are fired in paralell with the core stage to augment its thrust - hence the name. With Titan IV, the solids and first core stage were fired pretty much in series. The core stage ignited a few seconds before the solids separated. Therefore, the solids were acting as a stage not as boosters. --GW_Simulations_{User Page | Talk} 06:37, 18 May 2008 (UTC)[reply]

Astronautix [1] call them Stage 0, Spaceflight [2] call them booster and the core first stage, NASA [www.jpl.nasa.gov/news/press_kits/cassini.pdf] page 35-36 "Stage 1 ignition T= 0:02:12" meaning the core, fas.org [3] call them Stage 0, Jane's [4] "strap-on Solid Rocket Booster (SRB) motors were attached to either side of the first stage" etc. Regards, Necessary Evil (talk) 22:47, 19 May 2008 (UTC)[reply]

There is a picture - File:LR91-AJ-11 rocket engine - Thrust chamber.jpg, can it be used in this article? --miya (talk) 14:06, 19 December 2008 (UTC)[reply]

Number of first stage engines

There is a discussion at Talk:LR-87#Number of nozzles and Talk:LR-87#Affected articles that affects this article. Please discuss it there. Andrewa (talk) 23:41, 17 March 2014 (UTC)[reply]

This article is listed at Talk:LR-87#Affected articles as one of those affected by the proposal at Talk:LR-87#Consensus? to treat all variants of the LR-87 as a single engine with two nozzles. Please raise any objections to this there.

If no objections are received, the proposal will in due course take effect in this article. Andrewa (talk) 08:22, 26 March 2014 (UTC)[reply]

Serial numbers dont match

In 'Background' it talks about K-17 (failing in 1998) but in the table of launches it seems to call it A-20 - also for K-32 - Rod57 (talk) 20:25, 24 November 2018 (UTC)[reply]

What happened to the other 17 built

Article says 65 were paid for but the table only lists about 38 being launched. What happened to the others ? - Rod57 (talk) 20:29, 24 November 2018 (UTC)[reply]
