Introduction
The SEAL Pod is a range of Swimmer Delivery Vehicles.
They primarily exist to facilitate the insertion
and extraction of Special Operations forces and
equipment. In this role, their use allows for greater
stand-off from surface ships and submarines.
The vehicles have further application in the maritime
littoral space. These include specialist maritime
operations, mine countermeasures, counter-terrorism,
counter-narcotics, counter-piracy and maritime
protection operations.
SEAL Pod vehicles are surface or sub-sea craft, each
optimised for a particular deployment method or
mission profile.
The SEAL Pod range has been developed by leading
marine engineers from Sweden and the United
Kingdom.
Development, testing and trials have taken place in
the Stockholm archipelago, the Baltic Sea, Portland
Harbour and the waters off the west coast of Scotland.
The SEAL Pod combines the Swedish commitment to
safety-led design and the ship-building heritage of
the Clyde; all underpinned by a unique operational
pedigree.
JFD has over 30 years’ experience of operating safely
subsea.

SEAL Carrier
Sub SEAL
Torpedo SEAL
SEAL Carriers are primarily deployed from
a surface vessel and are able to cover large
distances at high speed. During the approach,
the vehicle may submerge to remain undetected.
Sub SEALs are primarily deployed from a host
submarine carrying personnel and equipment.
They remain fully submerged throughout the
entirety of their mission.
Torpedo SEAL can be deployed from a host
submarine’s torpedo tube or from any surface
vessel. They are rapidly deployable, easy to
operate and extremely cost effective.
Typically, they carry eight personnel.
Typically, Sub SEAL carries eight personnel.
Torpedo SEAL accommodates two personnel.

SEAL Carrier
SEAL Carrier Overview
Example Applications
SEAL Carriers operate in three modes; surface, semi-submerged
and submerged.
SEAL Carrier is controlled by two personnel; a Pilot and a Co-Pilot.
Launched from a surface ship, SEAL Carrier vehicles transit
at speeds of up to 30 kts on the surface before switching to
submerged mode for a clandestine final approach.
Surface propulsion is provided by an on board diesel engine and
water-jet. Submerged propulsion is delivered by thrusters and
powered by advanced Lithium Polymer batteries.
SEAL Carrier vehicles may be deployed from a number of host
platforms, including rotary and fixed-wing aircraft via the SEAL Air
Delivery System (Page 8).
Mission profiles may follow one of these examples:
Delivery of six -man combat team
Delivery of special forces effect
Rapid response counter-terrorism / counter-piracy
Maritime standing patrol vessel
Mine countermeasure operations
Host platform for Autonomous Underwater Vehicles
Remotely operated weapons platform

Secondary Deployment Options
SINC System
Air Drop
Submarine
Utilising the SEAL Air Delivery System, SEAL
Carrier vehicles may in future be deployed via
low-velocity extraction drop from a Boeing C-130
or similar fixed-wing aircraft.
Generally mounted behind the fin, SEAL Carrier can
be transported on a submarine in wet conditions at
depths of up to 150m.
The Steering Information Navigation Control system
is common to all vehicles in The SEAL Pod.
A medium-lift helicopter may also be used for low
altitude deployment, recovery and emergency
extraction.
SINC automates course, heading, depth and
levelling of the craft. SINC also manages navigation,
communications, electrical and hydraulic systems
as well as the transitions between surface and
submerged modes.
SINC reduces operator workload whilst increasing
vessel safety.

SEAL Carrier Variants
SEAL Carrier may be customised to
meet specific customer requirements,
particular mission profiles, or to meet
projected procurement budgets.
The following two examples illustrate
some of the ways in which a SEAL
Carrier may be optimised for greater
range, performance, payload
capabilities or cost-efficiency.
For more information, please visit
jfdefence.com
SEAL Lion
Smart SEAL
SEAL Lion is suited to mission profiles demanding
greater range, endurance and payload capacity.
Smart SEAL is shorter and lighter than a typical SEAL
Carrier. It can accomdate four passengers and two
crew.
The craft accommodates three crew and 16
marines and their equipment in stealth and dry
conditions during the final semi-submerged
phase of a landing operation.
No Export Licence Required
Smart SEAL caters for mission profiles with shorter
transit phases and less demanding payload
requirements.
This configuration makes a modest trade-off in
performance in exchange for greater cost-efficiency,
both up-front and through-life.
Smart SEAL is also suitable for civilian applications as
an export licence is not required.

Example Applications
Sub SEAL vehicles are primarily launched from a hangar attached to
the casing of a submarine and are released whilst fully submerged,
at depths of up to 30m. Once launched, Sub SEAL remains
submerged for the entire mission. The vehicles may approach, or
break, the surface for communication or reconnaissance purposes.
Sub SEAL is controlled by two personnel; a Pilot and a Co-Pilot.
The Co-Pilot is also the commander of the vehicle.
Power is provided by Lithium Polymer batteries and a vectoredthruster arrangement, affording sprint speeds of greater than seven
knots and a range of 50 nm.
Sub SEAL vehicles may also be deployed by surface craft or rotarywing aircraft.
A smaller variant of Sub SEAL may be transported within a
submarine’s flexible payload tube.
Their mission profile may follow one of these examples:

Delivery of special forces effect

Secondary Deployment Options
SINC System
Surface Ship
Helicopter
Sub SEAL may be deployed from a surface ship
using a crane, davit, A-Frame or moon pool
arrangement.
Medium-lift rotary-wing aircraft are suitable for the
insertion or extraction of an under-slung Sub SEAL
vehicle.
The Steering Information Navigation Control system
is common to all vehicles in the SEAL Pod.
JFD can provide launch & recovery systems to
meet specific customer requirements.
In this manner, Sub SEAL may be deployed or
recovered, at speed, across great distances and
below radar.
See page 26 for more information.
SINC manages course, heading, way-point navigation,
GPS, communications and reconnaissance
equipment. It provides mission status updates to
personnel in the rear compartment via low-light
display.
SINC reduces operator workload whilst increasing
vessel safety.

Sub SEAL Variants
JFD is able to customise Sub SEAL
vehicles to meet specific customer
requirements, particular mission
profiles, or to meet allocated budgets.
The following example illustrates the
most common way in which a Sub
SEAL may be optimised to operate at
greater depths and significantly reduce
passenger and operator fatigue.
For more information, please visit
jfdefence.com
Sub SEAL DRY is a one-atmosphere, pressurised
submersible offering greater depth of operation,
range and endurance than that of the typical ‘wet’
Sub SEAL.
The dry internal environment reduces passenger
and operator fatigue during the often lengthy
transits between the insertion point and the
intended area of operation.
The environment allows for the crew to
communicate, prepare for their mission and
maintain equipment during the transit phase.
Protected from the temperature of the external
water, the crew will also arrive at their target in a
better physical and mental condition than that of
a wet-transit crew undertaking a similar mission.

Torpedo SEAL Overview
Example Applications
Torpedo SEAL transits within a NATO-standard 533mm torpedo
tube. Once removed from the tube, Torpedo SEAL is fully extended
and ready for use.
Torpedo SEAL is controlled by a single pilot. It also accommodates
one passenger and equipment. The mission profile may follow
one of these examples:
It is then able to transport two divers and equipment, fully
submerged, over a range of 10 nm.
Torpedo SEAL may also be easily stowed within the multi-purpose
tubes being integrated into future submarine designs, or beneath
the outer casing of the submarine.
Extend the operating range of a combat team
Underwater survey and reconnaissance
Delivery of explosive ordnance
Counter-narcotics & harbour patrol
Torpedo SEAL
A fixed variant of Torpedo SEAL, without export licence
requirements, is also available.
Mine countermeasure operations

Dry Deck Shelter Integration
The integration of SEAL Pod vehicles with either a new-build or existing Dry Deck Shelter
greatly increases the overall range and effectiveness of a modern Special Forces capability.
Maintenance, mission configuration and preparation all take place at one atmosphere inside
the DDS during the transit phases to, and from, the area of operation.
