Development adapted the series from an existing screenplay by Kim Won-seok.|alt=Kim Eun-sook speaks into a microphone while seated at a press event in 2016. On February 18, 2014, Hwa&Dam Pictures announced that writers Kim Eun-sook and Kim Won-seok were collaborating on a series tentatively titled Descendants of the Sun. The project was described as a "humanistic blockbuster" melodrama set in disaster zones, a rarity in Korean drama history. It was originally slated to air on SBS. Planning began in 2011, though the project initially received a "not very bright" industry assessment due to its high budget and risky disaster-themed setting. Kim Eun-sook proactively reached out to Kim Won-seok to collaborate on adapting and revising his award-winning 2011 screenplay, Doctors Without Borders (). Through an open and collaborative process, the pair reconstructed the script, debating and editing ideas until reaching a consensus. They drew inspiration from the humanitarian efforts of World Vision, 119 emergency medical services, Médecins Sans Frontières, and the Republic of Korea Army Special Warfare Command. To strengthen the romantic and melodramatic elements, Kim Eun-sook changed the protagonist, Yoo Shi-jin, from a doctor to a special forces officer in the Republic of Korea Army. To ensure authenticity, Kim Won-seok and the film crew consulted with the ROK Army Headquarters and medical experts. In July 2014, Hwa&Dam Pictures transferred the project to Barunson Inc., with Next Entertainment World (NEW) serving as investor and distributor. Concurrently, Kim Eun-sook ended her twelve-year association with SBS. The network ultimately declined the series, In October 2014, KBS agreed to broadcast the series and began discussing production plans for the first half of 2015. Pre-production On November 13, 2014, Lee Eung-bok was announced as the director of Descendants of the Sun. While overseas production was initially planned for late 2014, To meet Chinese market requirements, the series was entirely pre-produced, a departure from the traditional Korean live-shoot model. While intended to improve production quality and actor immersion, this format risked mistimed brand sponsorships and precluded adjustments based on real-time viewer feedback. The production team called the move a financial necessity to ensure simultaneous broadcast in China, rather than a creative choice; they had originally seen partial pre-production as a more viable approach, since a full pre-shoot's extended schedule significantly increases costs beyond industry norms. Song Joong-ki accepted the male lead as his first role after military service, while Song Hye-kyo was reported to be a strong candidate as the female lead. Their casting garnered attention following their recent successes: Song Joong-ki in The Innocent Man (2012) and Song Hye-kyo in That Winter, the Wind Blows (2013) and My Brilliant Life (2014). On April 2, 2015, Song Hye-kyo, Jin Goo and Kim Ji-won were confirmed for their main roles. The cast featured Song Joong-ki as special forces team leader Yoo Shi-jin and Song Hye-kyo as doctor Kang Mo-yeon. Jin Goo played non-commissioned officer Seo Dae-young, and Kim Ji-won portrayed army surgeon Yoon Myung-joo. Later in April, SM Entertainment confirmed Shinee's Onew as a junior doctor under Mo-yeon. The following month, KBS announced the addition of Kang Shin-il and Seo Jeong-yeon; the former was initially cast as Yoo Shi-jin's father. Further additions included Jo Woo-ri as Onew's partner, Hyun Jyu-ni as Mo-yeon's friend, Lee Seung-joon as a senior doctor, and Lee Yi-kyung. Jo Jae-yoon was later confirmed to play an antagonistic construction manager. The production employed over 350 staff members. In October 2014, Hangzhou-based Huace Media bought a 13.03% stake in NEW for (), providing major funding ahead of the show's pre-production. By early June 2015, distribution rights were sold to China at a premium prior to filming, driven by the popularity of Kim Eun-sook and Song Hye-kyo, which helped offset production costs. Additional financial support was provided by Dal.komm Coffee and the Export–Import Bank of Korea. Filming The cast attended the first script reading for the series on May 28, 2015. Principal photography began on June 12 in South Korea, where filming took place for three months at various locations, including military bases and hospitals. The production received support from the ROK Army and the Ministry of Culture, Sports and Tourism. Scenes set in the fictional country of Uruk, inspired by Iraq, were filmed on a set in Taebaek and an indoor set in Anseong. Filming focused on the coastal scenery of Zakynthos, specifically Navagio Beach, the backdrop for a date scene between the leads. To meet the Chinese National Radio and Television Administration's deadline for simultaneous broadcast review, filming was scheduled to be completed in South Korea by December. Although most of his scenes wrapped late in the year, Ji Seung-hyun filmed his first-episode scenes in August. Principal photography wrapped on December 30, 2015. Post-production The production allocated to art design, with computer-generated imagery (CGI) for the Uruk landscape and earthquake sequences accounting for a significant, though undisclosed, portion of post-production costs. Visual effects (VFX) were used to create realistic scenes, depict dangerous sequences safely, and insert localized product placement for the Chinese broadcast. At a February 2016 press conference, the production team described the series as a story of "wonderful young people", noting that pre-production allowed for improving the script's quality; Kim Eun-sook called it her best "fantasy" script. The series had a production cost of , which was fully recouped before the first broadcast. == Thematic analysis ==

Descendants of the Sun blends romance, melodrama, and action genres; it explores themes characteristic of South Korean society, which scholars stated function as cultural diplomacy, making the series relatable to a global audience. The screenplay combines traditional values, loyalty, filial piety, and righteousness, with modern ideals of equality, independence, and international humanitarianism. In crises, the protagonists prioritize professional duty and life-saving over romance. Incorporating humor, the script relies on conventional melodrama and traditional gender-role division, in which "the man protects" and "the woman waits". The series portrays South Korea as a morally upright, developed peacekeeper and helps normalize overseas troop deployments as a natural part of Korea's global role. It resonates with the younger shinsedae (new generation), who are said to be conservative on security issues but more confident nationalists than earlier cohorts. By depicting an Arab League leader sympathetically and referencing 1970s Korean construction projects in the Middle East, the drama was positioned as an attempt to reach Arab markets for the Korean Wave. It portrays Korean reunification, the U.S.–South Korea alliance, patriotism, and social discipline regardless of status. Descendants of the Sun depicts the South Korean military in a fantasy-like manner, with no realistic internal violence, corruption, or oppression, and portrays it as an organization that nurtures youth and transforms lives. It has frequently been compared to a "drama version" of the variety show Real Man (2013–2016); while it presents an idealized military image, the series distances itself from daily barracks life and instead casts its narrative as a human melodrama centered on romance. Critic Kwon Chang-gyu noted that Yoo Shi-jin is characterized as an "honorable" soldier whose insubordination constitutes an ethical stance against state failure; such actions would likely violate military law and are viewed as unrealistic. Using non-verbal communication to convey humanism, the series portrays Confucian-influenced Korean culture. It depicts a paternalistic hierarchy in which seniors hold significant authority and have a duty to care for their subordinates, though this power can be abused to unfairly disadvantage them or pressure them into unethical situations. Descendants of the Sun utilizes various Korean cultural motifs, emphasizing the dominance of the Korean language in specific contexts. The presentation of kimchi in Uruk affirms Korean identity abroad and promotes the dish to global viewers as an entry point to "Korean-ness". The show also merges this culinary tradition with the photography culture of saying "cheese". By highlighting contemporary achievements while omitting South Korea's history of poverty and conflict, Descendants of the Sun frames overseas military deployment as a hallmark of the nation's modernized international status. Female characters wear modern attire that remains "polite and proper" by avoiding excessive exposure; this lack of Westernization allows audiences across Asian markets to feel a cultural attachment to the series. The fictional setting of Uruk and the show's title reference and mirror the Epic of Gilgameshs themes of power, glory, friendship, love, and mortality. The depiction of Korean-led development projects in Uruk reflects Seoul's nation-branding efforts; Patrick Flamm interprets these portrayals as public diplomacy intended to transition South Korea's international image from a "Korea discount" to a "premium brand". == Original soundtrack ==

Producer Song Dong-woon collaborated with music director Gaemi on the series' original soundtrack (OST). Song previously managed soundtracks for dramas including The Chaser (2012), ''It's Okay, That's Love (2014), Three Days (2014), Pinocchio (2014–15), and Who Are You: School 2015'' (2015). Selection began five to six months before the premiere; Song narrowed approximately 700 to 800 candidates to ten tracks by excluding those unsuitable for the production. These underwent extensive revisions, with choruses rewritten dozens of times to complement the series. The production company aimed to create a "well-made album with collectible value" rather than "consumable" digital tracks. The soundtrack's first release, "Always" by Yoon Mi-rae, serves as the love theme for the series' leads. "This Love" () by Davichi features piano and orchestral accompaniment to highlight the relationship between Seo Dae-young and Yoon Myung-joo. "Once Again" () by Kim Na-young and Mad Clown serves as a theme for Dae-young and Myung-joo, appearing during flashback sequences. The track features a hip hop beat with desperate rap delivery. K.Will's "Talk Love" () is a bright, medium-pop track featuring a whistling theme and rhythmic guitar; its lyrics address the "tug-of-war" of romance. "With You" by Lyn serves as a love theme for Shi-jin and Mo-yeon with an arrangement that intensifies to heighten emotional resonance. "By My Side" () by SG Wannabe is dedicated to Dae-young and Myung-joo, reflecting their tumultuous relationship through piano and orchestral accompaniment. M.C the Max's "Wind Beneath Your Wings" () features a shifting melody used during crises for the main couple. The final single, "How Can I Love You" by XIA, is a jazz ballad used during romantic scenes for both the lead and supporting couples. During the broadcast, Gaemi and director Lee Eung-bok re-recorded four major tracks to improve synchronization with the drama's scenes. These adjustments included changing lyrics and keys, with final mastering completed in the United States. Music&New released the soundtrack on CD in two volumes on March 24 and April 21, 2016, respectively. As of year-end 2016, according to the Gaon Chart, the albums sold a combined 80,198 copies in South Korea.

By March 23, 2016, the production had recouped its production cost and earned over in additional profit through export rights to 27 countries and various promotional activities. The OST also achieved significant success in China; on the music platform KuGou alone, the soundtrack package sold over 260,000 units, generating approximately in revenue by mid-April 2016. Critical response South Korea The series was a commercial and critical success in South Korea, praised for its acting, dialogue, and pre-recorded production style. Critics noted that the series updated the "disaster melodrama" genre; Lee Eun-joo of the Seoul Shinmun observed that while Kim Eun-sook maintained her "Cinderella story" tropes, she refreshed the narrative by featuring independent female characters and a professional military-medical context. Similarly, Kim Seon-young of Hankyoreh commended the show for blending espionage and medical drama to ground its romantic elements, appealing to a broader audience. Critics Jeong Deok-hyun and Yoon Seok-jin attributed its popularity to a fast-paced plot that replaced traditional love triangles with international conflict and natural disasters as primary drivers of tension. Jeong Deok-hyun noted that Song's post-military physical condition helped him effectively convey the show's themes. Kang Mo-yeon was praised as an "advanced" female character defined by shared growth rather than class conflict; however, Kim noted she became increasingly subordinate to the male lead as the plot progressed. While music critic Kang Tae-gyu praised the synergy between visuals and music, he found the show's "completeness" lacking due to production choices aimed at the Chinese market. Bae Seon-yeong of Sports Chosun offered a harsher assessment, labeling it Kim Eun-sook's worst work due to poor narrative logic, excessive product placement, and unimpressive CGI. International Lakshana N. Palat of The Indian Express attributed the show's success to the "electrifying" chemistry between Song Joong-ki and Song Hye-kyo, noting their ability to convey desire through glances elevated the series above "saccharine" romantic dramas. The Republican Post similarly praised the leads, while Marcus Goh of Yahoo! Life described the cinematography as a "visual feast", though he found the relationship between supporting characters Sang-hyun and Ja-ae more "organic" than the central romance. Critics also highlighted the show's thematic depth. Academic Chen Youjun argued the series transcended simple romance by framing the narrative against the conflict between national duty and medical ethics. Writing for Wen Wei Po, Yun Feiyang praised the series for blending realistic detail with "romantic illusion", specifically noting Kang Mo-yeon's "feminist consciousness" and proactive nature. The narrative received significant criticism, with Goh cited "ludicrous" obstacles, plot holes, and a "dated" musical score, while describing Mo-yeon as "shrill". Domestically, it became the first miniseries to surpass 30% in viewership ratings since MBC's Moon Embracing the Sun (2012), though its final ratings remained below the latter's peak of 42.2%. The drama set a precedent in an industry where ratings had been declining; while a show achieving in the mid-10% range was considered a success, Descendants of the Sun recorded a final nationwide rating of 38.8% and a capital area rating of 41.6%. Its audience share reached 58% nationwide and 61% in the capital area. Awards and nominations At the 52nd Baeksang Arts Awards, Descendants of the Sun won the Grand Prize for Television, and received nominations including Best Drama, Best Director, Best Actor, Best Actress, and Best Scriptwriter.

Both lead actors were awarded Presidential Commendations at the Korean Popular Culture and Arts Awards. Internationally, the drama gained the Best Drama Series title at the 21st Asian Television Awards, and Excellent Korean Drama at the 11th Seoul International Drama Awards. Controversies The series was criticized for blatant product placement (PPL). Following the plot's return to South Korea in episode 13, critics and viewers argued that the frequent appearance of products, including red ginseng, almonds, and automobiles, felt forced and disrupted audience immersion, particularly during high-stakes scenes. The Korea Communications Standards Commission (KCSC) subsequently reviewed the matter. Kim Won-seok denied political intentions regarding the show's perceived militarism, stating he aimed to depict a country's response to disasters. Kim acknowledged that PPL was not integrated into the storyline as seamlessly as intended. Following the premiere, viewers complained that loud background music obscured dialogue; producer Ham Young-hoon pledged to investigate and adjust the audio balance. In episode 8, a scene featuring the character Seo Dae-young swearing drew debate. Although some found the language contextually appropriate, the KCSC issued an administrative "recommendation" for violating broadcast language regulations. In Vietnam, the show's popularity sparked debate over South Korea's historical role in the Vietnam War. While one journalist argued the show ignored past war crimes committed by Korean troops, many viewers countered that the drama focused on a fictional UN peacekeeping mission unrelated to historical conflicts. Viewers identified several unrealistic plot points, such as a helicopter landing on a hospital roof to retrieve a captain, physically impossible car stunts, incorrect CPR technique, and the protagonist's disobedience of military orders. South Korean men who completed their military service described the drama as "far removed from reality", comparing its inaccuracies to "talking about science while watching a cartoon". Sports Q criticized Lee Chi-hoon's story arc as "forced", noting that viewers struggled to empathize with the character being labeled a coward for failing a rescue under impossible circumstances. == Legacy ==

Economic and cultural impact Descendants of the Sun generated substantial economic impact in South Korea in 2016. The Export–Import Bank of Korea estimated the series produced in economic effects, while other analyses, accounting for intangible benefits like national branding, placed its value at . The series shifted Chinese consumer behavior; viewers' demand for featured health supplements and fashion items drove an increase in online direct sales and tourism spending in early 2016. Following the 2015 lifting of a decade-long export ban, the series' depiction of samgyetang was credited with boosting the dish's popularity and exports in China. The series also benefited the Chinese streaming platform iQIYI, where paid subscriptions rose from 10 million to 15 million during the show's run. Chinese media estimated iQIYI earned at least in revenue from the series. Product placements saw surging sales in South Korea and China, leading major duty-free, cosmetic, and airline conglomerates to compete for the lead cast as models. Some affiliated beauty brands reported 50% sales increases, with featured products selling out globally. The series became a tool for national branding; lead actor Song Joong-ki was appointed the face of international tourism campaigns, and former filming sites in Taebaek and Paju DMZ were developed into tourist destinations. President Park Geun-hye remarked that the series stimulated foreign interest in Korean culture, later referring to South Korean UN peacekeepers in South Sudan as the "real descendants of the sun". Industry impact Descendants of the Sun was the first major Korean drama to center on peacekeeping operations, portraying South Korea as an active agent in global foreign policy. This marked a shift from earlier military series like Iris (2009) and Athena: Goddess of War (2010–2011), which focused on the inter-Korean conflict. The drama is regarded as a symbol of South Korea's emergence as a middle power, intertwining a fictional mission with national identity. Its commercial success made it a frequent subject of academic analysis, particularly in China, where researchers examine it as an example of using television to project soft power. Amidst the drama's success, Netflix announced plans to develop original Korean content while securing international distribution rights for the series. Lead actors Song Joong-ki and Song Hye-kyo, who initially denied dating rumors, announced their engagement on July 5, 2017. In response, the KBS Drama cable channel aired a two-day marathon of the series. The couple divorced on July 22, 2019. Adaptation In July 2016, a Chinese film adaptation produced by Huace Film & TV and directed by Zhang Yibai was announced, though it has yet to be produced. In the Philippines, the series was adapted as Descendants of the Sun: The Philippine Adaptation, which aired from February 10 to December 25, 2020. The cast featured Jennylyn Mercado, Dingdong Dantes, Rocco Nacino, and Jasmine Curtis-Smith. The Philippine adaptation won the Most Popular Foreign Drama of the Year award at the 15th Seoul International Drama Awards. A Vietnamese adaptation consisting of 48 episodes was broadcast from September 29 to November 19, 2018. Directed by Trần Bửu Lộc, the remake starred Song Luân, Khả Ngân, Hữu Vi, and Cao Thái Hà. The Vietnamese series received mixed reviews during its run. The Vietnamese Ministry of National Defence requested broadcaster VTC to correct inaccuracies in the series regarding the etiquette, regulations, and imagery of the People's Army of Vietnam. The broadcasting rights for the Vietnamese adaptation were acquired by iQIYI and Netflix, where it was re-edited into 24 one-hour episodes. == Notes ==
