DDG-1000 Program - 2014

In a January 2014 assessment, DOD's Director, Operational Test and Evaluation noted risks with the program's development and test strategy and recommended that the Navy develop a strategy to mitigate the risk of not delivering substantial mission capability until after final contract trials.

In September 2014, the Navy requested DOT&E concurrence to move FSST from the first ship of its class, DDG 1000, to the last of its class, DDG 1002. DOT&E disapproved the deferral request and opposed changing the schedule and test article resourcing within a TEMP revision. The Navy unilaterally removed the funding for the FSST and proceeded with their unfunded plan to conduct FSST on DDG 1002. In October 2015, the Navy revised their decision and agreed to conduct FSST (specific ship to be determined) prior to the first deployment of any DDG 1000 Zumwalt class destroyer.

Conducting FSST on DDG 1000 is critical to finding and correcting failures in mission-critical capabilities prior to the classes first deployment and prior to placing this class of ships in harms way. FSSTs routinely uncover mission-critical vulnerabilities that were not identified by component testing, analysis, and/or modeling and simulation alone. A component shock qualification program for assessing ship vulnerability to below-water threats is necessary for accurate damage simulations. However, the shock qualification program remains unfunded.

All three ships of the DDG 1000 Zumwalt class have in common a significant amount of new designs, including the unique wave-piercing tumblehome hull form, as well as the new Integrated Power System, Total Ship Computing Environment (software, equipment and infrastructure), Integrated Undersea Warfare System, Peripheral Vertical Launching System, the Advanced Gun System, and the associated automated magazines. These systems and equipment have not been subjected to shock on previous ship classes. Moreover, the previously untried automation and small crew for a ship this size, limit the sailors ability to conduct repairs to enable recovery from shock-induced damage.

UNDEX and AIREX vulnerability assessments lacked credible damage prediction models. The challenges and limitations in predicting ship vulnerability reinforced the need to complete FSST and component shock qualification before the first operational deployment of a DDG 1000 Zumwalt class destroyer.

As of September 2014, almost all of the equipment for the mission systems had been delivered and installed for the first and second ships, and the shipbuilder had begun energizing the ship's gas turbine generators a key element of the integrated power system. Once energized, the program can begin to activate and test the propulsion and electrical systems without reliance on power from the shore. The program reported that the multifunction radar was installed on the lead ship, but testing of modifications to the radar to include the volume search capability was still ongoing. The program estimated that the shipboard radar would not begin activation until late 2015.

According to program officials, seven software releases for the total ship computing environment had been completed to support lead ship activation and delivery, comprising 98 percent of the program's software development efforts. The program reported that land based testing of the advanced gun system and tactical guided flight tests of the long range land attack projectile had been completed.

As of September 2014, the program reported that construction of the first two ships was 92 and 79 percent complete, respectively. However, slower than anticipated progress with the shipboard test program and compartment completions delayed delivery of the lead ship's hull, mechanical, and electrical systems beyond the program's baseline schedule of October 2014. While the Navy had not yet approved a revised baseline or determined the cost and schedule impacts of the delay, delivery was expected in August 2015.
