CAMBRIDGE, MA – The TRIDENT II Weapons System was initially engineered to serve until 2027. When the Navy announced an initiative to extend its life to 2042, the challenge was to modernize the system and introduce life-extending modular design capabilities while continuing to meet the Navy’s stringent performance and budget requirements.
The U.S. Navy honored Steven J. DiTullio, who helped the service address these challenges as he oversaw the design and development of its MARK 6 guidance system, which is used in the TRIDENT II, as a senior leader at Draper, with its Fleet Ballistic Missile (FBM) Lifetime Achievement Award during a May 4 ceremony at the Washington Navy Yard.
According to the Navy statement, the FBM Lifetime Achievement Award recognizes industry partners who have demonstrated “technical brilliance, innovation, and expertise in their field,” and DiTullio’s work played a fundamental role in providing the United States with a credible and affordable sea-based strategic deterrent.
DiTullio, whose Draper career has so far spanned 33 years, is credited with his lifetime contribution to the U.S. Navy FBM program, including MOD1 guidance leadership of the Mk6 Life Extension Program and transformation of Draper into the guidance prime contractor for the Strategic Systems Programs. DiTullio is Draper’s vice president for strategic systems.
As the U.S. Navy’s strategic guidance prime contractor, Draper has designed and supported the guidance system for every fleet ballistic missile deployed since the program began in 1955. Mr. DiTullio continues to provide distinguished TRIDENT Guidance Program leadership and has achieved an exemplary record of successful program management, program execution, technology development, experimental systems implementation and production transition.
Draper develops novel PN&T solutions by combining precision instrumentation, advanced hardware technology, comprehensive algorithm and software development skills, and unique infrastructure and test resources to deploy system solutions. The scope of these efforts generally focuses on guidance, navigation, and control GN&C-related needs, ranging from highly accurate, inertial solutions for (ICBMs) and inertial/stellar solutions for SLBMs, to integrated Inertial Navigation System(INS)/GPS solutions for gun-fired munitions, to multisensor configurations for soldier navigation in GPS-challenged environments. Emerging technologies under development that leverage and advance commercial technology offerings include celestial navigation (compact star cameras), inertial navigation (MEMS, cold atom sensors), precision time transfer (precision optics, chip-scale atomic clocks) and vision-based navigation (cell phone cameras, combinatorial signal processing algorithms).
Draper combines mission planning, PN&T, situational awareness, and novel GN&C designs to develop and deploy autonomous platforms for ground, air, sea and undersea needs. These systems range in complexity from human-in-the-loop to systems that operate without any human intervention. The design of these systems generally involves decomposing the mission needs into sets of scenarios that result in trade studies that lead to an optimized solution with key performance requirements. Draper continues to advance the field of autonomy through research in the areas of mission planning, sensing and perception, mobility, learning, real-time performance evaluation and human trust in autonomous systems.
Draper develops precision instrumentation systems that exceed the state-of-the-art in key parameters (input range, accuracy, stability, bandwidth, ruggedness, etc.) that are designed specifically to operate in our sponsor’s most challenging environments (high shock, high temperature, radiation, etc.). As a recognized leader in the development and application of precision instrumentation solutions for platforms ranging from missiles to people to micro-Unmanned Aerial Vehicles (UAVs), Draper finds or develops state-of-the-art components (gyros, accelerometers, magnetometers, precision clocks, optical systems, etc.) that meet the demanding size, weight, power and cost needs of our sponsors and applies extensive system design capabilities consisting of modeling, mechanical and electrical design, packaging and development-level testing to realize instrumentation solutions that meet these critical and demanding needs.
Draper has developed mission-critical fault-tolerant systems for more than four decades. These systems are deployed in space, air, and undersea platforms that require extremely high reliability to accomplish challenging missions. These solutions incorporate robust hardware and software partitioning to achieve fault detection, identification and reconfiguration. Physical redundancy or multiple, identical designs protect against random hardware failures and employ rigor in evaluating differences in computed results to achieve exact consensus, even in the presence of faults. The latest designs leverage cost-effective, multicore commercial processors to implement software-based redundancy management systems in compact single-board layouts that perform the key timing, communication, synchronization and voting algorithm functions needed to maintain seamless operation after one, two or three arbitrary faults of individual components.
Draper has continued to advance the understanding and application of human-centered engineering to optimize the interaction and capabilities of the human’s ability to better understand, assimilate and convey information for critical decisions and tasks. Through its Human-Centered Solutions capability, Draper enables accomplishment of users’ most critical missions by seamlessly integrating technology into a user’s workflow. This work leverages human-computer interaction through emerging findings in applied psychophysiology and cognitive neuroscience. Draper has deep skills in the design, development, and deployment of systems to support cognition – for users seated at desks, on the move with mobile devices or maneuvering in the cockpit of vehicles – and collaboration across human-human and human-autonomous teams.
