Illustration: Xia Qing/GTRecent media attention has focused on Taiwan region's purchase of 66 F-16V (Blk 70) fighter jets from the US, the first two of which are now en route to the island. A mainland expert said the induction of these jets cannot change the cross-Straits air power balance. Their performance is comparable to the PLA's J-10C, but against the likes of J-16, J-20 and J-35, their tactical value is limited. The real gap, however, is not in individual aircraft, but in the PLA's already mature air combat system.
Taiwan region is beginning to receive the first operational aircraft from its 66-jet F-16V Block 70 order, reported Defence Security Asia on Saturday. The first two single-seat fighters, serials 6727 and 6728, departed the US on August 17, 2026, transited through Fort Worth and Hawaii, and were expected to continue through Guam before reaching Chihhang Air Base, weather permitting.
In addition to purchasing brand-new fighters, Taiwan region had previously cooperated with the US to upgrade 140 F-16A/B aircraft to the F-16V (Blk 20) standard. That upgrade work was fully completed in December 2023, according to CNA on August 19.
Taiwan region previously claimed that the F-16V (Blk 70), in addition to featuring increased thrust, airframe optimizations, extended range, and conformal fuel tanks, also enhances beyond-visual-range combat capability and partial stealth characteristics. It is equipped with an Active Electronically Scanned Array (AESA) radar, providing multiple functions including air-to-air search, tracking, weapons guidance, electronic warfare, and communications, according to the HK01.
The F-16V (Blk 70) is the newest variant of the F-16 family, Song Zhongping, a mainland military affairs expert, told the Global Times on Sunday. The PLA's mainstay fighters have already been widely equipped with AESA radars and are at the same technological generation as the F-16V (Blk 70). In comparison with the J-10C, both fall into the light-to-medium fighter category and have a degree of comparability.
However, comparing to a heavy fighter such as the J-16, and especially when facing fifth-generation aircraft like the J-20 and J-35 that possess a clear generational advantage, the F-16V has no edge at all. Constrained by its original medium-weight, single-engine design, the F-16V faces inherent gaps versus heavy fighters in range, payload, and upgrade potential, Song explained.
The expert pointed out that what decides victory or defeat is no longer the performance of individual aircraft, but the entire combat system behind them.
Modern warfare is no longer a matter of "soldier versus soldier, general versus general." The PLA's advantage lies in its comprehensively overwhelming system-of-systems combat capability. It is not necessary to shoot down an F-16V in the air, it can also be destroyed on the ground, by striking its shelters or cratering runways so that it cannot take off or land, Song said.
The F-16V does improve Taiwan region's individual aircraft capabilities, but once integrated into a system-of-systems combat environment, its ability to alter the overall situation is extremely limited, said Song.
A Xinhua News Agency report in March 2026 described how a certain PLA Air Force unit organized its three mainstay fighters, the J-20, J-16 and J-10C, to conduct multi-day-and-night air combat confrontation training covering situation sharing, coordinated strikes, electromagnetic countermeasures, and other subjects.
The Taiwan regional authorities' attempt to rely on these F-16Vs to "resist reunification by force" is no different from a mantis trying to stop a chariot, Song said.
From August 5 to 14, the Taiwan regional authorities conducted this year's "Han Kuang" military exercises. A CCTV News report on August 14 noted that the Taiwan region's Han Kuang exercises have become an annual farce. The entire exercise was plagued by continuous controversies.
The so-called "Han Kuang" exercises have always been a hollow, wasteful spectacle. The Democratic Progressive Party authorities are hereby warned: the "Taiwan independence" dead end leads nowhere and cannot be altered. The PLA remains on high alert around the clock, continuously enhancing its combat readiness against separatist and external interference activities. It is, and will always be, the solid foundation for safeguarding national sovereignty and territorial integrity, and for maintaining peace and stability across the Taiwan Straits, Senior Colonel Chen Xi, a spokesperson for the Ministry of National Defense, said on August 14.

8月18日晚，韦东奕时隔一年多更新B站账号，发布视频《一道有趣的数学题》，仅展示一道小学四年级数学题的解法，开头标注“韦东奕主编《数学能力》”。
E |
与此同时，其B站小店上架了两套练习册，《小学数学解题能力训练练习册》（1—6年级，售价39.8元）和《初中数学解题能力训练练习册》（7—9年级，售价49.8元），商品页面均以“韦东奕带你学数学”为宣传语，并配有韦东奕照片。
F | 练习册由韦东奕主编，龙门书局出版。上架之初，练习册销量仅为个位数。但随着话题发酵，销量呈指数级增长，21日晚间突破4000件，22日下午累计突破1.5万件，22日晚，小学版已售出超过2万本，初中版售出6000多本，合计超过2.6万件。按售价计算，仅B站小店单渠道销售额便已超过100万元。练习册上架初期，不少网友对账号及商品真实性表示怀疑。对此，北京大学方面回应媒体，确认该B站账号为韦东奕本人账号。练习册出版社龙门书局对媒体表示，该系列图书确实由韦东奕亲自主编。
G | 蓝鲸记者发现，韦东奕主编练习册的销售渠道并不限于其本人B站账号。
H | 龙门书局官方账号、韦东奕堂哥及堂姐的抖音账号橱窗均上架了该练习册，抖音平台还出现了名为“韦东奕图书”的店铺。
该店铺背后公司为“杭州奕数文化产业发展有限公司”，天眼查显示，公司成立于2026年5月22日，注册资本100万元，法定代表人曹恩铭。
与此同时，各大电商平台上也有商家在售该练习册。以抖音“伴学匠官方旗舰店” 为例，其相关商品链接已售出上万单。8月23日凌晨1点多，该店铺直播间仍有150余人在线观看。
考古加数据显示，带货期间该直播间卖出5000至10000单，销售额在25万至50万元之间。直播中，主播现场展示练习册内容，并称书中含“韦神手稿”等物料，评论区大量家长咨询。
