Welcome to US Warplanes, an internet guide to what is considered
the most definitive, decisive and enduring World War II,
Post World War II
(Cold War / Vietnam Era) & The Modern Era
(Gulf War and beyond) and Present Day military
aircraft of the United States Air Force, Army and Navy.

US is designed as a quick reference site for aviation
researchers and enthusiasts who are looking for a concise listing of
individual aircraft variants, conversions and serial numbers.
The site does not go into a detailed description of aircraft histories or
service and does not discuss any one aircraft's service history.

The website uses a variety of sources, these being published reference
books on aviation subjects, primary references from museums etc.,
magazine resources, email correspondence and general observation
of real aircraft at airports and airshows.

There are four main sections in each database - Service,
Variants, Production and Conversions.
The information below is a guide to how each of these
sections is constructed and presented.

The following are a few pointers that will make this website a little
more understandable for newcomers:

(1) The designation / serial number presentations are based on what
the aircraft was when it rolled out the factory door. Many types had
modifications, inter-service changes etc. post-delivery and these are
noted where possible.

(2) Initial US serial numbers are noted plus initial customer serial numbers
for foreign military sales etc. Second-hand and subsequent sales are
not recorded as this moves outside the scope of the website.

(3) Static test airframes that were issued with either a serial or construction
number are listed and counted in the final totals.

(4) Within each database, serial numbers are noted in the first column
followed by construction numbers then sub-totals and totals.

(5) The term "mixed XXX to XXX" means a group of serial or factory
numbers do not follow a normal numerical sequential order or it
has been too lengthy to type out the entire sequence - remember
this site is trying to remain relatively concise.

(6) The term "1+" in the conversions section refers to where the number
of actual conversions isn't known but it is certainly more than one.
Sometimes these conversions can run into the many hundreds.

This section introduces the aircraft type with various information like
the model, designation, names and the main time frames the type
was in production and service.

Manufacturer: This is the location of the manufacturer's MAIN CORPORATE HEADQUARTERS at the
time the first prototype flew, not the manufacturing plant(s) where production was undertaken.
Subsequent locations are also noted if the main headquarters was shifted DURING an aircraft's
production run.
Name changes of manufacturers are also noted if these occurred also DURING an aircraft's
production run, e.g. Consolidated to Consolidated-Vultee to Convair. 
Model: This is simply the manufacturer's own company designation for an aircraft type.
Greater detail of model designations can be found in the variant section. 
Designation: This is a rundown of all designations officially applied to an aircraft type across all
of the services - Air Force, Army and Navy. Designations in use by close-ally
countries are also included.
Name: This lists the OFFICIAL name(s) of a type as bestowed by the Air Force, Army or Navy,
it does also list unofficial names, e.g. Blackbird (SR-71), Aardvark (F-111), but does not
list nick-names or slang expressions. Names in use by close-ally countries are
also included.
First official flight: Basically the first flight of the prototype aircraft. If the prototype was a conversion
from an earlier model, e.g. XP-40, XC-119, the official flight of the first production aircraft is
also listed.
Factory production period: This spans the time in years from the construction of the first prototype to the last
year of production of the last variant.
Primary service period: This is an aircraft's main, front-line service period, not the entire service period it was
on active duty. Most aircraft have a primary service period before being outdated by
a newer model and becoming obsolete or assigned to second line duties.
Aircraft assigned drone duties, (e.g. QF-102, QF-4), are not included as these aircraft
have been written-off so to speak and are not technically in service.
Last official flight: An aircraft types last assigned mission before being finally retired completely from
active duty, e.g. although the B-29 was no longer a front-line aircraft by 1953,
its last official flight was not until 1960.

This part presents a list of an aircraft's NEW BUILT variants as they were
designated when they came off the production line. Some designations were
changed after delivery due to service reassignment or Lend-Lease etc. and these are
listed where possible.

The year of first flight is in the first cell.
Model numbers are presented in bold in the second cell.
Designations of variants are listed in bold in the third cell.
Subtotals (where required) are listed in the second to last cell.
Totals are listed in bold in the last cell.

1949 Model MS-8 XCG-20 2 Total: 002
1953 Model F-205 C-123B 307 Total: 307
1955 Model F-205 YC-123E 1  
1957 Model F-205 YC-123H 1 Total: 002

Grand Total: 311

The Production section is a rundown of the variants presented above
but with a brief description attached of important information.
The variant's production period and plant location(s) with their
two letter codes are also listed along with the serial numbers
and construction numbers of that particular plant location.

Models or variants not built are listed in Italics.

Serial numbers are presented in the first cell.
Construction numbers are presented in the second cell.
Sub totals (where required) are in the third cell.
Variant totals are presented in bold in the last cell.

As XC-123, squared tail, rounded cockpit windows,

the 16th delivery squared rear cockpit windows.

Some tables include cancelled order details plus other additional information
such as Lend-Lease deals or changes of designation.
Block numbers are not included on this database.

These are the NEW BUILT variants converted to a secondary role
such as tankers, cargo conversions, VIP transports etc.
It's also for aircraft that have had a change of designation by either
armed service (Air Force, Navy, Army etc.), or a change of country

Secondary conversions are presented in brackets underneath the
original conversion.

Proposed designs or cancelled conversions are presented
as italics.

Aircraft in bold type have three separate categories:
The first are prototypes that contribute a significant development to that aircraft
type. The second are production conversions that also contribute a large development
to that aircraft type, e.g. KB-29P, C-123K, C-141B etc. The third are conversions with
a newly assigned designation e.g. C-108 (B-17), C-109 (B-24) or F-61 (P-61) etc.

Conversion designations are presented in the first cell.
Numbers converted are presented in the second cell.
The third cell contains a brief description along with any
newly assigned model numbers, names or serial numbers.

Listing block numbers is a major task on any scale and is outside the scope of this web site which is
only aimed at giving an overall view of the variants, factory locations, production periods and numbers built
of any particular aircraft. Block numbers are only listed with photo captions.

There were many hundreds of aircraft types developed and tested by the US Armed Forces over the years
since aircraft became a formidable form of combat.
Some never got off the drawing board and others only made it as far as the prototype stage - for these reasons
this part of aviation history is another story and non-production aircraft are not included on this web site.
