USS Robert Smalls

She first deployed in March 1991, to the Persian Gulf in support of Operation Desert Storm.

Chancellorsville was next deployed from February to August 1993, to the Persian Gulf as part of the Nimitz Battle Group. On 26 June 1993, Chancellorsville launched strikes on the Iraqi Intelligence Center in Baghdad with nine Tomahawk missiles in retaliation for the aborted assassination attempt on former President Bush. She deployed again to the Western Pacific and Persian Gulf from April to October 1995.

Following a Fifth Fleet deployment to the North Persian Gulf in 1995, Chancellorsville was awarded the Spokane Trophy in 1996. The Spokane Trophy is awarded by Commander-in-Chief, United States Pacific Fleet to the surface combatant ship considered to be the most proficient in overall combat systems readiness and warfare operations.

Chancellorsville deployed to the Caribbean and Eastern Pacific in support of joint counter-narcotics operations in November 1997. During this deployment, she rescued the crew of an Ecuadorian fishing vessel which had been adrift for ten days. Upon her return home, Chancellorsville underwent her first major nine-month overhaul in San Diego, California.

On 7 July 1998, Chancellorsville changed homeport from San Diego, to Yokosuka, Japan, joining Task Force 70/Battle Force Seventh Fleet, and probably, Carrier Group Five. After arriving in Yokosuka, Chancellorsville participated in multinational operations in the Sea of Japan, including the International Fleet Review. Chancellorsville took part in exercises with the Kitty Hawk Battle Group in the spring of 1999.

On 6 April 1999, Chancellorsville deployed to the Persian Gulf in company with Kitty Hawk and Curtis Wilbur in support of Operation Southern Watch, and returned to Yokosuka on 5 January 2000. In May 2000, Chancellorsville participated in exercises with the Thai and Singaporean navies.

Following a visit to Qingdao, China, in August 2000, Chancellorsville took part in ANNUALEX 12G, a joint U.S.-Japanese naval exercise. In November, Chancellorsville fired guns and SM-2 missiles as part of MISSILEX 01-1. In March through June 2001, she visited Singapore, Thailand, Saipan and Sydney, Australia, as part of an extended Spring Cruise. Chancellorsville then entered dry dock for an upkeep period in the fall.

In September 2001, Chancellorsville deployed with the Kitty Hawk Battle Group in support of Operation Enduring Freedom, operating in the theater for several months.

Chancellorsville paid her first visit to Vladivostok, Russia, in July 2002, celebrating Independence Day in Russia along with Fort McHenry.

In March 2003, the ship was assigned to Carrier Group Five.[13] On 22 October 2003, Chancellorsville played host in Guam to two warships of the People's Republic of China, which made the first-ever visit of the Chinese navy to Guam. By May 2004, she was back in the Southwest Asian region, where she lent aid to a disabled Indonesian fishing boat.

On 19 July 2004, Chancellorsville departed Yokosuka to participate in Exercise Summer Pulse 2004 and Joint Air and Sea Exercises (JASEX) 2004, with the Kitty Hawk Battle Group. Summer Pulse was the Navy's first implementation of the new Fleet Response Plan (FRP). She returned to homeport 7 September.

Chancellorsville entered a nine-week dry dock availability in February 2005. Following the maintenance period, she immediately returned to sea to participate in the exercises Talisman Saber 2005, the third annual Orange Crush and the Joint Air and Sea Exercise (JASEX) 2005. She returned to Yokosuka in August. ANNUALEX 2005 commenced in November with Chancellorsville participating, along with other U.S. and Japanese assets. The exercise saw a total of 61 naval vessels, including two U.S. submarines, 10 U.S. Navy ships and 49 Japanese ships. Chancellorsville visited Hong Kong at the end of November and returned to Yokosuka 12 December. Chancellorsville swapped with Shiloh based in San Diego. Chancellorsville's homeport was changed to San Diego, with Shiloh moving to Yokosuka. The crews remained in their respective locations.

In winter of 2006, Chancellorsville deployed again into the Western Pacific, visiting Singapore and Pattaya, Thailand, in February. In April, she joined forces of the Republic of Korea for Reception, Staging, Onward-movement, & Integration and Foal Eagle 2006 (RSOI/Foal Eagle 06), exercises utilizing more than 70 U.S. and Korean ships. Chancellorsville returned to Yokosuka in August in preparation for a hull swap with Shiloh. Chancellorsville was scheduled to return to San Diego, in October 2006, making it her homeport once again.

In March 2011, in company with the carrier Ronald Reagan, Chancellorsville was deployed off northeastern Honshu, Japan, to assist with relief efforts after the 2011 Tōhoku earthquake and tsunami.[14] During that time, helicopter crews from Ronald Reagan were exposed to leaking radiation from the nuclear accidents and ships from the carrier strike group were moved to avoid being downwind from the facility.[15]

During the latter half of 2012, Chancellorsville underwent equipment upgrades as part of the Aegis Modernization effort ACB-12. In January 2013, the ship spent five days[16] under way off the coast of California to perform a series of tests of the updated ACB-12 equipment and software.

In November 2013, while testing combat weapons systems off the coast of Point Mugu, California, a BQM-74E unmanned drone being used in the exercise failed to respond to commands to turn away from the ship and collided with Chancellorsville. Since it was a tracking exercise and not a live fire exercise, the crew did not engage the drone with the Phalanx CIWS.[17] Two sailors received treatment for minor burns and the ship suffered some damage and returned to San Diego for assessment.[18][19] The damage later proved to be more severe than initially assessed. Citing Navy sources, the U.S. Naval Institute reported that repairs to the ship would cost $30 million and take six months to complete.[20]

On 7 June 2019 Chancellorsville came close to a collision with the Russian destroyer Admiral Vinogradov. Each side blamed the other for the near collision.[21] Russian sources stated that the incident occurred in the southeast of the East China Sea while US sources named the location as in the Philippine Sea.[21] According to retired US Navy captain Carl Schuster, the Russian ship's wake shows that it "didn't adhere to either the rules of the road or the incidents at sea agreement."[22] United States Seventh Fleet spokesman Commander Clayton Doss said the Russian destroyer came within 50 to 100 feet (15 to 30 m) of Chancellorsville, "putting the safety of her crew and ship at risk."[23] The Russian Navy released a statement claiming that Chancellorsville had "suddenly changed its course and crossed the Admiral Vinogradov destroyer's course some 50 meters away from the ship."[24] According to the same statement, this caused Admiral Vinogradov to take an "emergency maneuver" in order to avoid a collision with the American ship.

In November 2019 and again on 15 February 2020, the ship transited the Taiwan Strait.[25]

During the 2020 George Floyd protests, the name of the ship came into question because it honors a victory of the Confederate Army fighting against the United States for southern independence and in defense of slavery.[26] In December 2020, the U.S. Navy's Report to Congress on the Annual Long-Range Plan for Construction of Naval Vessels stated that the ship was planned to be placed Out of Commission in Reserve in 2026.[27]

In May 2022, Chancellorsville was homeported out of Yokosuka, Japan. She was as part of Carrier Strike Group 5 led by the carrier Ronald Reagan.[28] On 28 August 2022, Chancellorsville along with sister ship Antietam conducted a routine transit through the Taiwan Strait. This was the first such transit to occur since the 2022 visit by Nancy Pelosi to Taiwan.[29]

The ship was officially renamed Robert Smalls on 1 March 2023.[1] Robert Smalls deployed with the Ronald Reagan carrier strike group in May 2023.[30] Robert Smalls made a port visit to Da Nang, Vietnam in June 2023.[31] Robert Smalls participated in exercise Talisman Sabre 2023 in July 2023.[32]
