It's at the discretion of the Secretary how the name is adopted. In broad strokes, last names were preferred for Admirals and Naval Heroes while full names were preferred for Presidents and significant civilians. Full names have become more common but Secretary Winter left "Elmo" off Zumwalt.

Raytheon Company has delivered critical mission systems early for the U.S. Navy's DDG 1000 Zumwalt-class destroyer.
The ship's first Total Ship Computing Environment (TSCE) data center and AN/SQS-60 mid-frequency sonar array were delivered two and eight months ahead of schedule, respectively.
"The early delivery of these ship systems continues our history of stellar performance on this complex program as we effectively manage the transition from development to production while remaining on cost and on schedule," said Raytheon Integrated Defense Systems' (IDS) Kevin Peppe, vice president of Seapower Capability Systems.
"We are committed to the ongoing development and delivery of these highly capable and effective mission systems that will, without a doubt, make DDG 1000 the most advanced surface combatant in the world," he said.
The TSCE data center comprises two ruggedized Electronic Modular Enclosures that house and protect the open architecture computing environment for DDG 1000's combat and ship control systems. When integrated onboard the ship, the TSCE data center will provide DDG 1000 with more data processing and storage capacity than existing U.S. Navy destroyers. TSCE will manage the ship's advanced systems, including the AN/SQS-60 mid-frequency sonar array.
AN/SQS-60 is part of DDG 1000's AN/SQQ-90 advanced undersea warfare combat system and is scheduled to be installed on the Zumwalt in August 2011. The SQQ-90 tactical sonar suite represents a major advancement in undersea warfare capability and will provide broad warfighting coverage for the DDG 1000 class. Raytheon IDS is the SQQ-90 systems integrator, bringing together the full functionality of the suite's sonar elements. The SQQ-90 comprises the AN/SQS-60 hull-mounted mid-frequency sonar; the AN/SQS-61 hull-mounted high-frequency sonar; and the AN/SQR-20 multifunction towed-array sonar and handling system.
Raytheon Delivers US Navy's First Dual-Frequency Sonar
Electronics delivery completes DDG 1000's advanced hull-mounted sonar suite
NATIONAL HARBOR, Md., April 16, 2012 /PRNewswire/
Raytheon Company completed delivery of the electronics for the AN/SQQ-90 tactical sonar suite, the complex sonar for the first ship of the U.S. Navy's DDG 1000-class multimission destroyer. The AN/SQQ-90 tactical sonar suite, the first dual-frequency hull-mounted sonar of the Navy's surface fleet, is a major advancement in undersea warfare capability and will provide broad warfighting coverage to DDG 1000.
Raytheon delivered the sonar electronics completely assembled and integrated into an Electronic Modular Enclosure (EME), an innovation to 21st century shipbuilding designed into the Zumwalt-class destroyer program for affordability. The EME delivers benefits not only in upfront integration and testing before delivery to the shipyard for ship installation, but also minimizes the footprint occupied onboard the ship (size and weight) and maximizes efficiencies in both power and cooling.
The AN/SQQ-90 comprises the AN/SQS-60 hull-mounted mid-frequency sonar; the AN/SQS-61 hull-mounted high-frequency sonar; and the AN/SQR-20 multi-function towed array sonar and handling system. Raytheon is the AN/SQQ-90 systems integrator, bringing together the full functionality of the suite's sonar system elements. Through automation and unique information management, DDG 1000's AN/SQQ-90 can be operated by one-third the crew of current Aegis platforms.
"The AN/SQQ-90 is, without a doubt, the most advanced integrated undersea warfare system in the world," said Kevin Peppe, vice president of Seapower Capability Systems for Raytheon's Integrated Defense Systems business. "Integrated with DDG 1000's open architecture combat system and multi-sensor capabilities, AN/SQQ-90 will provide superior operational performance in both the littorals and deep waters against a multitude of targets, including mines and quiet diesel submarines."
Innovation in Ship Systems Integration
EMEs are large subsystem assemblies that efficiently package the shock mitigation, electromagnetic interference protection, thermal conditioning, security and vibration isolation for commercial off-the-shelf electronics integrated inside. The sonar electronics EME contains the fully assembled, integrated and tested electronics to power and control the ship's hull-mounted sonar, including the transmit/receive amplifiers and associated processors that distribute signals and data to the ship's command center.
