SeaSnake 30
... is a remote-controlled weapon station (RCWS) / close-in
weapon system (CIWS) for mounting on ships. It is based on
the Oerlikon KCE30 30 mm revolver cannon, and was designed
by a request of the German Navy. It is capable of employment
of air burst ammunition (ABM).
As one of the most modern carbon-based weapon stations
available on the market, with an aviation-derived,
high-performance KCE-30 revolver cannon, it enables both -
rapid response capability through high pointing dynamics and
high assertiveness in combat through enormous firepower and
intelligent assistance systems. The truly modular system
approach allows for individual system combinations for a
customized configuration even in harsh environmental
conditions (IP56). The SeaSnake30 weapon station is ideally
suited for the main armament of smaller patrol boats and
supply vessels or as a secondary caliber gun for corvettes
or frigates.
The SeaSnake30 can be operated either as an integrated
system via the CMS or as a stand-alone concept with its own
control panel.

SeaSnake 27 (or MLG 27 4.0)
... is a remote-controlled, semi-automatic, stabilized CIWS
defense system with an optionally integrated or detachable
E/O sensor unit on a stabilized pan and tilt platform that
can be moved and steered independently of the weapon. The
multi-target tracker integrated in the system represents
state-of-the-art technology at the highest level and
enables, among other things, simultaneous multiple target
tracking and automatic target recognition. The bus system
used in the SeaSnake, which facilitates the integration into
a Combat Management System. In addition, the SeaSnake can
also be operated independently as a “stand-alone” system.
The reduced weight, lower silhouette and compact stealth
design, in combination with its outstanding performance,
favours the SeaSnake as primary armament for smaller vessels
such as patrol boats and speedboats or as secondary armament
for larger ships such as corvettes and frigates. The modular
architecture enables the integration indepen dently of ship
types. The Mauser BK27 (27x145 mm) weapon unit is capable of
deploying various types of ammunition with a high rate of
fire and great precision. Different operating modes offer
the possibility to choose between single shot and manually
adjustable bursts (length&cadence) or system supported in
automatic mode.
The automatic firing mode optimizes the hit probability
while reducing the amount of consumed ammunition depending
on the distance and size of the threat. The ammunition
technology of the Frangible Armor Piercing Discarding Sabot
(FAPDS), as a sub-caliber ammunition with high kinetic
energy, supports the high penetration capability upon impact
and a high splintering, cascading effect with cascading
damage effect in the depth of the target. It was developed
as combat ammunition specifically for the SeaSnake 27 in its
multi-role deployment and is characterized by a high
efficiency against a variety of threats.
Performance:
High rate of fire and ammunition efficiency
High precision
Flexible integration options (CMS&ship type)
Reduced ammunition consumption

SeaSnake 20
... is an improved remote controlled, semi-automatic, fully
stabilized 20mm medium caliber light naval gun system with a
mounted or detachable EO/IR-sensor array (SeaVision®) on a
pan&tilt sensor platform. The sensor platform can be
controlled and directed inde pendently from the gun cradle’s
present position or gun bore line. The new
multi-mode-multi-target tracker (MM-T) reflects
state-of-the-art technology and enables the system for
simultaneous, numerous target tracking while offering the
flexibility of a semi-autonomous target selection. STANAG
interfaces ease the option for integration into the CMS or,
selectively, the choice of a “stand-alone” effector,
utilizing standard power supply sources with no deck
penetration required. The light-weight, low signature
solution favors the SeaSnake20 System as a main armament for
smaller vessels (i.e patrol boats) or as side armament for
larger vessels (corvettes, frigates) with an increased
flexibility of positioning for maximum effect due to the
carbon-based reduced weight and space required for
installation. The navalised, reliable KAE 20 mm gun has a
high rate of fire and great precision while offering new
operational modes from a single shot capability up to
flexibly timed bursts and controlled, automated releases for
optimum hit probability at reduced ammunition consumption in
relation to target size and distance. Latest Rheinmetall
ammunition technology and a well-balanced compromise between
weight, size, kinetic energy and effectiveness augment the
20mm medium caliber layout. The 20mm APDS-T (Armor Piercing
Discarding Sabot-Tracer) round represents a sub-caliber
kinetic energy round with a high velocity and high
fragmentation effect upon impact and therefore especially
tailored for the gun’s multi-role, naval application. The
upgraded ballistics, a short reaction time and new fire
control features qualify the SeaSnake20 as a weapon of
choice against a wide array of targets, including asymmetric
threats.
Performance:
High rate of fire
High accuracy & lethality
Flexible integration into CMS
Reduced ammunition consumption

SeaVision
... is a stabilized electro-optical sensor platform with
automatic target recognition (ATR) and multi-target tracking
features, especially designed for naval applications. The
sensor system can be used either gun mounted or ship
mounted. The outstanding stabilization, accuracy and
resolution out of an integrated high-precision gyro assembly
enables the use even on small boats and ships. The SeaVision
supports the full spectrum of naval operations from
surveillance through detection, threat evaluation, target
designation and fire control up to battle damage assessment.
The consequent use of light weight material like carbon
fiber results in an overall weight, which allows easy
installa tion - even in the ships mast.
The SeaVision comprises a sensor configuration designed for
long range detection and identification and generation of
accurate 3D target track-data via:
- Infrared camera
- HD colour TV daylight camera
- 2 x laser range finders using different technologies
Consequently, the generated 3D target-data can be used for
direct gun fire control applications. The design of the
SeaVision strictly followed the goal to achieve a very high
availability rate, thus ensuring safe use of the system even
in critical operational conditions.
This concept leads to the integration of COTS/MOTS
components in the sensor-system where possible, combined
with measures to reduce complexity to increase availability.
The SeaVision comprises an infrared camera of cooled
technology. The specific design of the IR-optics combined
with the use of long-life-cooler-technology and state-of-the
art detector technology leads to a high video-resolution and
high availability even under rough environmental conditions.
The SeaVision comprises a fix-optics HD colour TV-camera
with smart-zoom functionality. The HD colour TV-camera
integrates 3 cameras in a single unit. This leads to an
accurate alignment at all zoom-levels, which is required for
precise direct gun-fire control. Furthermore, waiving of
zoom-optics increases the reliability and increases the
switch-over times between different FoV’s. The SeaVision
comprises two different laser range finders.
Combining the advantages of both technologies, the
twin-laser configuration offers:
- Automatic internal range verification
- Confident laser measurement
- In-operation redundancy to support availability even in
critical operational conditions.
