Session I SSGN

Prompt Reactive Interdiction Strike Missile
by Tim Czerniak and Conrad Do11oh11e
of Northrop Grumman Mission Systems

ABSTRACT- The Missile Defense Agency (MDA) is developing an intermediate range BMD system (common booster) to fill capability gaps with a missile designed to intercept targets during their most-vulnerable boost-ascent phase of flight. This mobile system will also hold regional/national ballistic missile threats at risk that cannot be engaged by fixed systems such as the Ground-Based Interceptor (GBI) during all phases of exo-atmospheric flight. Northrop Grumman Corporation (NGC) has invested in a detailed examination of additional prospective missions for this fast, energetic, long-range missile. The top candidate is for a Prompt Global Strike missile coined “Precision Rapid Interdiction Strike Missile” (PRISM).

MDA and the Navy (N86 & N87) have jointly sponsored an Alternatives Assessment (AA) for near term fielding of common booster capability in sea-based platforms. During the conduct of this study, it was determined that the dimensions of this booster are physically compatible with the Ohio Class SSBN/SSGN launcher system and that ballistic missile defense operations by these submarines are feasible. This work has provided the technical foundation for integration of PRISM into the SSGN/SSBN weapons system. This Prompt Global Strike missile has a flight profile that will enable it to be readily discriminated from the Trident 05 missile, thus mitigating the risk of a responsive attack due to ambiguity following detection of a Conventional Trident Missile launch.

This paper presents a detailed technical summary of the booster development, required launcher modifications, command and control requirements and expected system performance.

SESSION II Tactical Survival

Full 360-Degree Tactical Awareness with the Non-Hull Penetrating,
Non-Rotating, High Resolution Digital Periscope Sensor Head
by Dr. Terry Huntsberger et al of Jet Propulsion laboratory,
Califomia Institute Of Technology

ABSTRACT- NA VSEA PMS 435 has identified the need for a nonhull penetrating, high-resolution (HR), continuous Field of View (CFOV) non-rotating {NR), 360┬Ědegree view and display of the sea surface and sky background from a periscope with integrated capabilities for:

Continuous observation of contacts (potential targets) Automatic detection and tracking of contacts (potential targets)
Recognition of contacts (threat determination) Ability to digitally zoom to any area for closer inspection

A High-Resolution, Continuous Field-of-View, Non-Rotating Imaging Sensor (HR/CFOV /NRIS) system will need to concurrently carry out a number of diverse visual tasks including search and detection, tracking, recognition, and multi-target cueing.

Search and detection missions require wide field-of-view (FOY) tracking that will need to address fast frame-rate data output from regions of interest (ROI), recognition requires high spatial resolution, while multi-target cueing requires all four tasks concurrently. The use of optical zoom is a much less efficient way of carrying out these diverse tasks for the HR/CFOV/NRIS, since manual zooming cannot simultaneously provide narrow and wide field of view scene visualization. It will be both difficult and time consuming for an operator to quickly zoom in and out of the ROI because of the vast changes in the FOY during zooming and relocating contacts within the search FOY that may be 50x higher than the narrow one.

The Jet Propulsion Laboratory (JPL) is developing a HR/CFOV /NRIS advanced demonstration model (ADM) for NA VSEA PMS 435, that provides a 360-degree, electronically selectable, low and high-resolution fields-of-view of the battlefield environment. The ADM is integrated with a JPL-developed Contact Detection and Analysis System (CDAS) that automatically scans the full 360-degree FOY of the high resolution imagers and extracts contacts based on tuned matched filters. These contacts are then processed for identification using a software emulation of a gray scale optical correlator (GOC) combined with a radial basis function neural network (RBFNN).

JPL demonstrated a fully populated 360-degree HR/CFOV /NRIS in July of 2007. Basic contact RO Is were autonomously nagged, recorded into a databse, and displayed; and a GUI allowed user selected and automated electronic zoom of ROIs. This talk will give details of the HR/CFOV /NRIS design, and will detail the field demo of the fully populated sensor head with a contact identification pipeline fully integrated into the automated target recognition algorithms in the CDAS.

Submarine Support of the Sea-Mobile Kinetic Energy Interceptor
Missile Defense Mission
by Benjamin Tritt, NSWC Dalgren; Hank Lee, MDA Kinetic
Energy Interceptor Program Office; Michael Graham,
Missile Defense Systems Engineering Team and Kevin Curtis
of Johns Hopkins University Applied Physics Laboratory

ABSTRACT- The Sea Mobile Kinetic Energy Interceptors (KEI) Platform Alternatives Assessment (AA) was a joint MDA-Navy study completed in 2007 that evaluated multiple, maritime platform alternatives (including surface combatants, submarines, and large deck surface ships) for hosting the sea mobile KEI system. In forming a platform recommendation, the AA study defined the platform alternatives with an integrated KEI capability and examined the performance of platforms in different scenarios against different platform threats and ballistic missile threats. The AA study conclusions and recommendations combine the platforms performance with a force structure assessment, general suitability comparison, Rough-Order of Magnitude life cycle cost estimations, development to IOC schedule comparisons, and risk assessments to recommend a sea mobile KEI platform. The end result of the platform study was a strong preference for the submarine platform as the host for the KEI system.

This presentation will describe the Alternatives Assessment study process and results with particular attention to:

  • Dependencies on different ballistic missile defense missions (boost, ascent and midcourse intercepts)
  • Unique challenges for the submarine such as timelines, communications and launch environments, and the proposed solutions
  • CONOPS and KEI system changes to optimize the submarine approach
  • Architectures and commonality with a land-mobile KEI system
  • Multi-mission capability evaluation
  • Submarine-unique risks and disadvantages
  • Submarine-unique advantages including availability and endurance, design reference mission and crewing, shore infrastructure, large missile integration, survivability, and certain aspects of force structure impacts

Virginia Class Efforts to Expand Mission Capability Starting with Block IV
by Alan Blay & Thomas Plante, Electric Boat & Byron Rose, NavSea PMS 450

ABSTRACT – As 21st century warfighting requirements evolve, combatant commanders continue to call for expanded mission capability from existing military platforms. The integration of additional types of payloads on nuclear submarines allows the ability to capitalize on the platform’s inherent stealth and durability to meet
these new warfighting requirements.

This paper describes an integrated spiral development approach to the Virginia Class that brings enhanced mission capability through payload development and ship design changes starting with Block III. Four focus areas are addressed as part of the integrated improvement strategy that balances recurring and non-recurring cost with capability enhancement: Design For Capability, Design for Life Cycle Affordability (DF-LCA), Design For Crew Effectiveness and continuation of Design for Affordability (DFA). The goal of this integrated strategy is to maintain the ship SCN cost neutral. Major capability initiatives addressed include, Virginia Payload Tube Launch and Recovery Arm, Att Payload Tube Bottom Drop, Manned Access to Att Tube, and Flexible Payload Sail. Cost reduction initiatives addressing procurement and life cycle cost reduction include: CA YES Wide Aperture Array (W AA), continued electrification of ship hydraulic systems, rotary electromagnetic launcher, warfare management and ship infrastructure improvements. Lastly, the synergies, efficiencies and complementary aspects of SSGN and Virginia Class Block III and IV payload capability development will be discussed.
