Discovery Military made a bold statement yesterday saying, "the B-1b is the fastest aircraft in the world on the deck....There isnt a single manned aircraft that can catch the B-1B at sea level"...

Truth? Or Mythbusted?

I havent looked it up yet, but IIRC the B1b's top speed was somewhere around 900 MPH. Maybe they meant in reverse?

Unless they are comparing the B-1 to similar aircraft I think there are quite a few planes that are faster than the B-1.
old site, upto 1994
http://www.fas.org/nuke/guide/usa/bomber/b-1b.htm
Speed: 900-plus mph (Mach 1.2 at sea level)

http://en.wikipedia.org/wiki/B-1_Lancer
Unlike the B-1A, the B-1B made no attempt at Mach 2+ speeds, although its F101-GE-102 engines are somewhat more powerful than those of the B-1A. Its maximum speed at altitude is Mach 1.2 (about 950 mph or 1,330 km/h), although its low-level speed, Mach 0.95 (about 700 mph/1,118 km/h) is superior to the B-1A's Mach 0.85. Technically, the current version of the aircraft can exceed its speed restriction, but not without risking potential damage to its structure and modified air intakes which were developed to make the aircraft more stealthy.

Performance
Maximum speed: Mach 1.25 (950 mph, 1,330 km/h)
Combat radius: 2,993 nm (3,445 mi, 5,543 km)
Maximum range: 6,478 nm (7,456 mi, 11,998 km)
Service ceiling: 60,000 ft (18,000 m)
Wing loading: 167 lb/ft² (816 kg/m²)
Thrust/weight: 0.37

I'm not sure what the record was but we set a few world speed records about 2 years ago for it's class of air craft. The sucker was loaded for bear with MK84 bombs and broke 49 or so world records in 2 days at the air show.

F-14, F-15, FB-111, Tornado, all claim Mach 1.2 @ sea level...

SU-37 says 870 mph @ sea level

900 for the B-1 seems like they may have a valid claim.

so far I cant find much that shows speed at sea level, they all show speeds at altitudes like 15,000 feet or higher.
but
http://home.iae.nl/users/wbergmns/info/f15.htm
has this for the F-15, but it maybe incorrect because I saw other sites that had this speed listed for 33,000 feet

Power Plant: Two Pratt & Whitney F100-PW-100 turbofan engines with afterburners.
Speed: 1,875 mph (Mach 2.5-plus at sea level).
Ceiling: 65,000 feet (19,697 meters).
Crew: F-15A/C: one. F-15B/D: two.

Airscrew i think they're putting it in prespective for the lay man by giving them a perspective they might understand. I don't think those are performance numbers at sea level for the Eagle.

Sea level standard day speed of sound is 761 mph.

2.46M is the number that comes out to with but I'm almost certain that the number is at altitude.

To push that fast at sea level is really a feat with the denisty of the air you'd be moving through.

I believe the Russian look alike is supposed to be faster...I can't really remember the designation or NATO name for it right now...believe it was a Tupolev TU-something.

Biggest problem with pushing it that fast on the deck, F-15 or otherwise - your gonna overheat the engines pretty damn quick. I think the F-4 got around this by using Water Injection, one of the reasons some Recce varients got upwards of 80,000 feet for 10 minutes at a time.

The B-1b isn't even supersonic at sea level. Basically all 3rd generation jet fighters and newer are faster.

at sea level?

seriously I think they are referring to the class of air craft.

You're all wrong

Unfortunately, all I can say is that the B-1 is quite fast and carries a lot of gas. The available literature does not come close to telling the whole story.

jerk.

spill the beans!

i am guessing it does mach 10 at sea level and is based on the technology recovered from Roswell.

I SAW THE SAME SHOW HE ia taking about. and they did state: the B1B was the fastest aircraft in rthe world "on the deck" nothing else could touch it. and they were refering to it out running fighters!

LOL because when i heard it i thought the same thing! "No way dude your high!"

Dinger · « **Reply #14 on:** September 01, 2006, 02:12:57 PM »

Yeah, unlike the A-20, which was slow on the deck.

Let's face it, anyone who's been to the SW US and had an "interesting experience", or anyone who's been at airshows, knows the B-1B is designed to be the NOE champ. Plus, if you read any of the first-hand reports coming out of Afghanistan, you know that the B-1B can go plenty supersonic plenty low on the deck. It may need a full-burner divv
Now, think BATS and Sensor-Fuzed-Weapons. You want some badass sum***** flying NOE supasonic so he ain't heard.
