Models
were built in the UK as series 'A' for the North American market and
'B'
for the rest of the world. Originally manufactured by
DeHavilland,
later Hawker Siddeley, later British Aerospace, some aircraft were
marketed
in North America as the Beechcraft Hawker BH125, a name that was to
reappear
when production was sold to Raytheon Beechcraft in 1993. For a
time,
British Aerospace made the 125 production into a separate division,
Corporate
Jets, and renamed the aircraft as the Corporate Jets CJ125, until the
company
was sold to Raytheon. Fuselages for the Hawker 800 are currently
produced in Wales and flown to at the Beechcraft company airfield in
Wichita,
Kansas for completion. In March 2007 the company was sold for 3.3bn
dollars to an investment group who renamed the company as
'Hawker-Beechcraft' and quickly announced plans for new models.
The
125 series was built in two versions, the -A version for the US market
or any country which accepts FAA certification and the -B for the CAA certification/
rest of the world. Few aircraft switch between the two as the cost
of converting B to A models is around 100,000 dollars, with conversions
from A to B is generally considered to be prohibitive. The A version
systems are measured in inches and pounds whereas the B uses metric values.
Other differences include the requirement for a stall warning system and
modification to passenger oxygen systems.

The
model 1 first flew on 13th August 1962. It has five cabin windows each
side and some aircraft were later re-engined with Garrett TFE731
turbofans, designated as -1/731's. There was no ventral fin
on this model. |

Powered
by Bristol Siddeley Viper 522 engines, this was built as a 6-8 passenger
aircraft with a range up to 1338 miles, further than the 1, made possible
by the addition of an extra fuel tank in the underside of the rear fuselage.Several
125-3's were later re-fitted with TFE731-3 turbofans by Hawker Siddeley
and designated the -3/731. |

The
400 series lacked the cockpit bubble of the earlier versions but included
other improvements from the series 3. As with the other models, some were
re-engined with TFE-731's, being designated -F400's . |

71
of the 600 model were built , replacing the 400 and differed by having
a fuselage stretch of 2 feet allowing space for an extra window, plus a
revised nose and tail profile. They are powered by the more powerful, but
noisy Rolls Royce Viper 601 turbojets giving a range up to 1,876 miles.
Accommodating up to 14 passengers, the 600 prototype was first flown on
21st January 1971. |

A
small number of 600's were re-engined with TFE-731-3's by Hawker Siddeley
and designated F600's
<
GBFAN was the prototype F600, originally having been built as a 400 series
model. |
.
 |
External
differences between the 600 and 700 were mainly limited to the larger TFE731-3
turbofans on the 700, although the F600 is almost identical. 215
of this model were built, with construction numbers in the 257001-257215
range. The aircraft accommodates up to 14 passengers and first flew
on 28th June 1976. It has a range of around 2,785 miles. |
.
 |
The
800 can be most easily differentiated from the 700 as it has no ventral
fin and a greater sweep of the tail. Further differences include
a greater wing span and deeper fuselage. Over 270 of the basic aircraft
were produced before the XP version was introduced. It first flew on 26th
May 1983. |

Several
U-125A models have been produced for the Japanese Self Defence Force as
patrol aircraft. The aircraft are modified 800 variants. |
.
Six 800
models were produced for the US Air Force as the C29A for operation in
the flight inspection role, although they were all later transferred to
the Federal Aviation Authority for use in a similar role, albeit still
operated by the military
.

A
stretched version of the 125 was produced as the BAe1000, later becoming
the Hawker 1000 on the aircraft's acquisition by Raytheon. Just over
50 were produced. It first flew on 16th June 1990, can carry up to
fifteen passengers and is 33 inches longer than the 800, allowing for seven
windows on each side. Powered by two P&W305 turbofans it also
has a longer range than the 800. |

Around
20 early HS125's were built as navigation trainers for the Royal Air Force
and designated as Dominie T1's. They were based on the HS125
series 3 but differed externally from the civil version by having
an extended wing centre section fairing housing Decca Doppler electronic
equipment, plus a ventral fin, six windows on the port side and four starboard.
First flown in December 1964, they are powered by Bristol Siddeley Viper
301 turbofans. Several aircraft are still operated in the role, even
though they are some of the oldest 125's flying. |
