The EH 101 has its roots
in a UK project to replace the Sea King. The design was later
revised to meet Italian navy as well as Royal Navy requirements.
Westland and Agusta established European Helicopter Industries Ltd,
which received formal go-ahead in February 1984 for nine prototypes
and subsequent development of what now became the EH 101.
The first
prototype made its maiden flight in October 1987.
Aside from its
principal anti-submarine warfare role, the EH 101 is also envisaged for utility and
transport missions. Some roles can be performed using the same basic
fuselage as the naval helicopter but, alternatively, the EH 101 can
be fitted with a modified rear fuselage incorporating a ventral
ramp/door. Systems and equipment vary with role and customer.
The
initial Royal Navy variant is the Merlin HM.Mk 1 which is equipped
with a Blue Kestrel 360°
search radar. The first of 44 on order was delivered in 1998. The
Italian navy EH 101s (16 on order plus eight on option) are powered
by GE T700-GE-T6A engines, each rated at 1 714 hp (1278 kW).
In
2000 the RAF began to receive the first of 22 Merlin HC.Mk 3
medium-lift transports. These can accommodate a maximum of 45 troops
or up to 6 tons of freight carried internally or as a slung load.
The first customer for the utility variant was to have been Canada,
which ordered 15 EH 101s for search and rescue duties, along with 35 naval
variants. The entire Canadian programme was subsequently cancelled
on budget and political grounds, but, in January 1998, the Canadian
government placed a new order for 15 examples of the revised AW320
Cormorant SAR version for delivery between 2000 and 2003. Further
development of the EH 101 could result in an airborne early warning version of the type
required by both the Italian navy and Royal Navy.
