Lockheed XB-30 – projekt ciężkiego bombowca który powstał w zakładach Lockheeda jako odpowiedź na zamówienie USAAF na "very heavy bomber" (bardzo ciężki bombowiec) – w wyniku tego zamówienia powstały dwa inne ciężkie bombowce Boeing B-29 Superfortress i Consolidated B-32 Dominator. Projekt nigdy nie wyszedł poza pierwszą fazę, wykonano tylko pierwsze rysunki i pomniejszony model tego samolotu, niemniej doświadczenie zdobyte przez Lockheeda w początkowej fazie projektu zaowocowało w późniejszym czasie dwoma innymi samolotami Lockheed Constellation i jego wojskową wersją Lockheed C-69 Constellation.

USAAC Roundel 1919-1941.svg
Roundel used by the United States armed forces from 19 August 1919 to 6 May 1942 until red dot removed to avoid confusion with Japanese insignia. Superseded very similar roundel whose colors and proportions differed slightly - the original version having the colors from the US flag, and a center dot 1/3 of the outer radius. This version has a center dot constrained by the inner vertices of the star, a size that does not translate into an even fraction.

US roundel 1942-1943.svg
Roundel used by US armed forces from 6 May 1942 to 28 June 1943 when white bars and a red outline were added as the result of studies which showed that shape was more important than color from a distance.

Roundel used by all US armed forces from 31 July 1943 to 14 January 1947, replacing roundel having red outline, or no outline, but with white bars, and was replaced some nine months before the USAF was formed, by roundel having a single lengthwise red bar inset in white bars (bisecting them), giving the insignia the trio of red-white-red stripes evocative of the non-canton areas of the Flag of the United States.
