Houthis have a strategic reserve of various advanced drones and modern missiles that have been tested and will be disclosed later on, rebel spokesman Yahiya Abu Sarei said on Sunday.
He told reporters this "2019 will be the year of drone air force and self-dependence and on [dependence] on expertise and capabilities in war industries," which he claimed made qualitative strides in manufacturing unmanned aerial vehicles.
Anad attack "came in retaliation to constant aggression and siege," Abu Sarei added at press conference in Sana'a. "If aggression stops, our forces will by sure stop such legitimate operations.
Last Thursday, Houthis attacked military parade in al-Anad Military Base with a bomb-laden Qasef 2-K drone, leaving six Yemeni troops killed, including head of intelligence Mohammed Saleh Tamah who died of injuries on Sunday.
Rebel spokesman said their troops "have second and third generations of the same Yemeni-made" Qasef.
He claimed that Houthis have new system of 100% Yemeni-made drone air force which "radars cannot detect, as well as inception systems. UAVs' fatal range is 80X30 and semi-fatal is 150X50 meters."
Houthi forces have now "drones able to penetrate fortifications," he said noting that their air force soon would be able to launch more than operation at the same time.
Yemen has been racked by an armed conflict that broke out after the Iran-backed Houthis had ousted the internationally recognized government late in 2014.
The conflict escalated after a Saudi-led coalition intervened militarily in the country in March 2015 to reinstate the government of President Hadi, leaving tens of thousands killed, hundreds of thousands injured, and 3 million displaced.
The war has pushed the country to the world's worst humanitarian crisis, according to the UN, with more than two thirds of the 28-million population in need for a type of humanitarian aid and immediate protection, including 8.4 million people unsure how to get next meal, and some 2 million children suffering severe shortage of nutrition.
