B21 (New York City Bus)
The Metropolitan Transportation Authority (MTA) operates a number of bus routes in Brooklyn, New York, United States; one minor route is privately operated under a city franchise. Many of them are the direct descendants of streetcar lines (see list of streetcar lines in Brooklyn); the ones that started out as bus routes were almost all operated by the Brooklyn Bus Corporation, a subsidiary of the Brooklyn–Manhattan Transit Corporation, until the New York City Board of Transportation took over on June 5, 1940. Of the 55 local Brooklyn routes operated by the New York City Transit Authority, roughly 35 are the direct descendants of one or more streetcar lines, and most of the others were introduced in full or in part as new bus routes by the 1930s. Only the B32, the eastern section of the B82 (then the B50), the B83, and the B84 were created by New York City Transit from scratch, in 1978, 1966, and 2013, respectively.

The B21 and all derived engines are often referred to as ''red block'' engines for the red paint applied to the block. The primary differences when compared to the B20 was the switch to a SOHC in place of the older pushrod configuration, and an aluminum crossflow cylinder head versus the iron head of the B20. History Initially the overhead camshaft versions were offered as optional equipment on the 240, becoming standard in all markets by the 1976 model year. The overhead camshaft motors were available in displacements of 2.0 (B19 and B200), 2.1 (B21), and eventually 2.3 (B23 and B230) litres. The B21 featured an stroke, and bore. In the US, the B21's power output ranged anywhere between and , based on variations in the compression ratio and was typically supplied with a B or M camshaft.

B-21 (machine)
The Northrop Grumman B-21 Raider is an American strategic bomber under development for the United States Air Force (USAF) by Northrop Grumman. As part of the Long Range Strike Bomber (LRS-B) program, it is to be a long-range, stealth intercontinental strategic bomber for the USAF, able to deliver conventional and thermonuclear weapons. The Air Force is planning to replace the Rockwell B-1 Lancer and Northrop Grumman B-2 Spirit with the B-21 by 2040, and could possibly replace the Boeing B-52 Stratofortress after that. The Air Force began planning for the B-21 in 2011 and awarded the major development contract in 2015. The B-21 is expected to make its first flight in 2023 and enter service by 2027. Many aspects of the B-21 program are highly classified; the program is designated as a special access program. The Congressional Research Service noted in 2021 that the B-21's technical details and specifications, such as speed, enabling systems, "size, required stealth, struct ...

Boron-21
Boron (5B) naturally occurs as isotopes and , the latter of which makes up about 80% of natural boron. There are 13 radioisotopes that have been discovered, with mass numbers from 7 to 21, all with short half-lives, the longest being that of , with a half-life of only and with a half-life of .
