How do you completely shield 78 MegaWatts of power? The DDG-1000 is releasing 78 million Joules per second. Where does the energy go? Some of it is transferred into the propellers, which partially generates a lot of acoustic energy. A portion of the 78 MegaWatts is radiated as infrared energy, which a Chinese C-802 anti-ship missile can easily detect (see citation below).
Excerpts: "dual guidance, which include: radar and imaging infrared guidance, television and imaging infrared guidance, dual band (infrared and imaging infrared) guidance, and television and infrared guidance."
"A datalink associated with the radar seeker and the dual radar and infrared guidance seeker armed C-802 was added enabled the missile to receive target information provided by aircraft and this later became a standard feature."
"Based on the datalink associated with the radar seeker, a newer datalink that was compatible with all three types of seekers was also successfully developed, enabling the missile to significantly improve its attack capability by allowing the pilot of the aircraft or the crew of the ship to view the images provided by the television or the imaging infrared seekers, and thus to select the potential targets, just like the way A-10 pilots used the images provided by the imaging infrared seekers of AGM-65 Maverick Air-to-surface missiles for targeting during the Persian Gulf War."

"As the imaging infrared seeker and the television seeker are significantly smaller than the radar seeker, the manufacturer has taken advantage of the extra space to develop a variety of combined seekers for dual guidance, which include: radar and imaging infrared guidance, television and imaging infrared guidance, dual band (infrared and imaging infrared) guidance, and television and infrared guidance. These combined seekers can also be fitted at naval bases. According to domestic Chinese news media the manufacturer says that as of the last quarter of 2006 no orders for had been received for any of the combined seekers except the radar and infrared guidance, due to funding problems.
A datalink associated with the radar seeker and the dual radar and infrared guidance seeker armed C-802 was added enabled the missile to receive target information provided by aircraft and this later became a standard feature. The first successful test fire of the C-802 with the datalink was conducted with Harbin SH-5 ASW equipped with British radar, and soon after, with Y-8X Maritime Patrol Aircraft equipped with Litton Canada radar. This datalink was originally developed for YJ-83/C-803, the successor of the YJ-82/C-802, and adopted for the YJ-82/C-802 upgrade.
Based on the datalink associated with the radar seeker, a newer datalink that was compatible with all three types of seekers was also successfully developed, enabling the missile to significantly improve its attack capability by allowing the pilot of the aircraft or the crew of the ship to view the images provided by the television or the imaging infrared seekers, and thus to select the potential targets, just like the way A-10 pilots used the images provided by the imaging infrared seekers of AGM-65 Maverick Air-to-surface missiles for targeting during the Persian Gulf War. Land attack capability is the greatest beneficiary since mobile targets on land can be engaged as a result, though only when the missile is equipped with television and imaging infrared seekers, but not the radar seeker. Like the datalink only associated with the radar seeker, the newer datalink allows the operators to alter the course of the missile and change targets after launching. However, there are no reports to support the claim that the operator can terminate the attack via the datalink like that of the Harpoon missile. This new datalink has very little difference from radar seeker associated datalink it is developed from in terms of hardware, the major difference is the software programs."
