delayed until mid-2013, and when the fi rst
production airframe was spotted, it was again
powered by the trusted Russian AL-31FN
turbofan.
The most likely reasons for the J-10B’s delays
are problems related to the new avionics,
which include a new fi re-control radar, and
the engine. The radar is thought to be an
X-band passive electronically scanned array
(PESA) type developed by the No 607 Institute
and said to be the fi rst such type developed
for a Chinese fi ghter. Initially it seems the
J-10B was planned to be equipped with an
active electronically scanned array (AESA)
developed by the 14th Institute, but this radar
was not ready and the PLAAF decided to
introduce a slightly less capable version fi rst.
In the meantime it also became clear that
the fi rst batch of J-10Bs use AL-31FN Series
3 engines, which have increased thrust and
reliability compared to the earlier AL-31FN.
The fi nal serial version is expected to be
powered by the WS-10B after its reliability
problems have been resolved. Based on
images from late 2014, the J-10B Block 01
extends to around 48 aircraft that have now
been built and are soon to be delivered.
An initial batch will most likely equip an
operational conversion unit at the PLAAF’s
Flight Test and Training Base, while a second
batch was expected to be delivered to a fi rst
front-line unit as this issue went to press.
In parallel to the steadily increasing
number of serial J-10Bs spotted at Chengdu,
an additional prototype was identifi ed
for the fi rst time in late December 2013,
numbered ‘2-01’. At fi rst it was unclear if this
was simply the fi rst aircraft from a newly-
established second production line or the
prototype of a rumored further upgraded
multi-role variant designated J-10C. Re-
numbered ‘1051’ in December 2014, it seems
most likely the aircraft is indeed the J-10C
prototype. This version will probably feature
enhanced avionics including the AESA
radar, greater use of composite materials,
and the WS-10B. Currently, though, it is still
powered by an AL-31FN Series 3. Externally,
J-10B and C versions are almost identical,
except for a few different blade antennae
on top of the fuselage and below the front
section as well as ahead of the vertical tail.
Based on the latest reports, the Block 02
J-10C will supersede the Block 01 J-10B
on the production line and no additional
B-models will be produced. As such, the
future seems bright for the ‘Firebird’ in PLA
service. If the milestone wasn’t already
achieved in 2014, this year production will
reach the 300 mark.
