of Broadband Sonar Advanced Processing System
(BSAPS) hardware and software. The current
transducers mounted on the hull will stay, resulting in
a cost efficient, but highly effective upgrade.
Thales will also supply and install a replacement
underwater telephone (UWT) system. Both systems
will be fitted in Auckland from early 2016, before the
frigates proceed to Canada for their full upgrades.
As already noted, NZ contracted for MBDA’s
Sea Ceptor which provides anti-shipping missile
defence. This defensive missile uses compressed
air to be launched vertically from the deck to 30
metres height, whence its rocket motor fires and off
it goes to the intercept point. (For more information,
including details of the intercept guidance system,
see “Different frigate combat system upgrades each
side of the Ditch” APDR June 2014.)
Ultra Electronics recently announced that its UK
sonar systems business has been awarded a contract
from NZ MOD, worth £9.9m ($A18m), for the
provision of two Sea Sentor Surface Ship Torpedo
Defence (SSTD) systems.
The SSTD system is a single in-line towed
array solution utilising a passive tow for detection,
classification and localisation of the threat posed to
a ship’s safety by incoming torpedoes fired from a
hostile submarine or aircraft. The system features a
flexible towed body countermeasure able to decoy
and jam all torpedo types, including wake-homing
torpedoes, and optional launchers can further deploy
Airborne Systems Europe has advised the defence
market that the RNZN will join their counterparts in

The FDS3 corner reflector decoy offers a unique
countermeasure protection against the most advanced

Foreign Military Sales cases have been established
with the US Government for the provision of
Multifunctional Information Distribution System
(MIDS) Low Volume Terminals (LVTs), COMSec
equipment and Link 16 systems.
The NZ MOD, NZ Trade and Enterprise and LMC
continue to work together to identify opportunities
where local NZ industry can
contribute to cost-effective support
of the upgraded vessels.
OPV NAVAL GUN
Both RNZN Offshore Patrol Vessels
(OPV) have had the guns upgraded,
with Rafael Typhoon 25mm
stabilised close-in gun systems
now in place of the previous MSI
DS25M AUTSIG 25mm weapon.
The system is capable of traverse
of +/- 120 degrees and elevation
between –12 .5 to +40.5 degrees.
Stabilisation accuracy of 0.2 mrad
means the weapon can continuously
land rounds within 20cm of the
aiming point at 1,000 metres range.
Recent test firings from both
OPVs have confirmed the success
of the upgrade. "The aim of the trials
was to verify that the installed Rafael
Typhoon Weapon System functions
correctly firing live ammunition at
a towed target," said Lieutenant Commander Vicki
Rafael's Toplite multi-sensor optronic payload,
which incorporates a laser designator, advanced
correlation tracker, and a forward-looking infrared
sensor, was also installed on both OPVs, replacing
the former Vistar 350 day/night surveillance system.
While the OPVs can carry a Super Seasprite
SH-2G(I) maritime combat helicopter, it is unlikely
that these lightly armed and relatively unprotected
vessels would be sent into serious harm’s way. The
Super Seasprites on an OPV would be restricted
to surveillance and lodging or collecting military
personnel, civilians, or supplies. It is thought a lack
of Link 16 equipment on the OPVs also means
the OPV cannot take advantage of the Super
Seasprite’s superior sensors. A better capability for
normal patrolling and surveillance at much lower cost,
currently under consideration, is an unmanned aerial
vehicle (UAV) which could be launched from, and
recovered on, the helicopter deck.
The two OPVs have proved invaluable and are heavily
utilised by the RNZN from the tropics to Antarctica.
With the National Party returned in September 2014’s
NZ elections, it will be interesting to see if the new
Defence Minister, Hon Gerry Brownlee, makes good
his predecessor’s pre-election suggestion that he
would go to Cabinet mid-2015 with a request for a
third OPV to be delivered by 2019.
Thales (Australia) will supply an upgrade of the current Spherion B sonar
system with the addition of Broadband Sonar Advanced Processing
System (BSAPS) hardware and software.
