The Request
• A conceptual design for a High Speed Assault
Connector (HSAC) to enhance Joint
Expeditionary Logistics (JELo) flow from the
Sea Base to shore
• Augment or replace existing connector
platforms
• Employment requirement
–
–
–

–
5/29/2016
Cargo: ~8000LT of vehicles, troops, and gear
Distance: 200nm from the Sea Base to shore
Time: 10 hours
Sea state: 4
Interface: accept cargo and troops at the Sea Base
and deliver to shore
High Speed Assault Connector Brief
5
The Design Solution
• A system of 12 HSACs that fill all the previous
connector requirements
• Each HSAC is multi-mission capable, selfsustaining, and:
– Can accommodate embarked troops, cargo, and
gear from FLS and or/CONUS to the Sea Base
– Can transit 2000nm @20kts (fully loaded) w/40% fuel
remaining
– Has defensive and offensive combat capabilities

Initial Requirements
• SEA-6
– Transport JEB from the Sea Base to shore
– Time limited to a 10 hour period
– Interface with Sea Base, developed ports, and austere
beaches
• TSSE Faculty
– Support amphibious operations ashore in addition to
delivering payload
– Conduct secondary missions
– Capable of independent operations
5/29/2016
High Speed Assault Connector Brief
8
Assumptions
• HSAC will move entire surface component of
JEB
– 2 Battalion Landing Teams (BLT)
• HSAC fully loaded prior to employment phase
• HSAC transit protected by the Sea Shield
provided by Sea Base forces
• Landing operations will be conducted in
reduced threat environments
• Boat lanes will be mine free
5/29/2016

9
Beachable/Non-Beachable
• Considered two delivery methods
– Beachable
– Non-Beachable (LCAC ferry)
• Conducted feasibility study on both
5/29/2016
High Speed Assault Connector Brief
10
Non-Beachable Feasibility
• Pros
–
–
–
–
Information readily available
Few tactical changes required
Improves effective LCAC range
Proven, beachable, high-speed connector
• Cons
–
–
–
–
5/29/2016
Large number of LCACs required
LCACs approaching end of service life
Inadequate availability/reliability
Additional interface in the loop
High Speed Assault Connector Brief
11
Beachable Feasibility
• Analysis of Newport class LST
– 3000LT payload
– 16 ft draft
– Bow ramp and stern gate
• Pros
– Performed similar mission
– Large craft can be made beachable
– Newer technologies will greatly enhance the
capabilities of previously proven designs
– Provides a single connector solution
• Cons
– Structural issues for bow ramp/beaching
– Possibly hull form limiting
• Beachable design selected

Analysis of Alternatives
•
•
Developed 3 Measures of Performance (MOP)
Analytic Hierarchy Process (AHP) was used to set the
weights
– Transport factor – 43%
– Survivability – 43%
•
•
•
Number of ships – 50%
Overall ship length – 30%
Speed – 20%
– Mission flexibility – 14%
•
•
•
•
•
5/29/2016
Payload – 30%
Draft – 30%
Number of ships – 20%
Speed – 20%
Overall MOP weighted sum of the individual MOPs

Design of Experiments
• 7 x 9 x 5 Design matrix
– 7 different hull types
– 9 different payloads
– 5 different speeds
• Total of 315 possible designs
• Initial ship characteristics calculated using
software from Maritime Applied Physics

• Highly reliable on effective Sea Shield protection
• Advantage of distributed multiple platforms for a
combined blanket of protection for increased
survivability
• Cooperative Engagement Capability (CEC)
• Multi-Function Radar (MFR)
5/29/2016
High Speed Assault Connector Brief
72
Cooperative Engagement Capability
• System of hardware and software that allows the
sharing of radar data on targets among ships.
• Each ship uses identical data processing
algorithms resident in its cooperative engagement
processor (CEP), resulting in each ship having
essentially the same display of track information
on aircraft and missiles.

MFR
• Multi-Function Radar
• Essentially the SPY-3 radar currently in
development
• 3D system capable of both air and surface
detection and tracking
• Fire control radar and missile control through
mid-course guidance and terminal homing
• Optimized for the littoral environment
– Superior clutter rejection

• TSSE acknowledges that we were unable to
perform a thorough analysis on all technical
issues that exist with every ship design
• TSSE believes that to achieve the HSAC
mission displacement craft such as the Joint
