「The ULTRA lander, to be used from Mission 3 onward, expands on this design and is currently designed to carry a payload of up to 200 kg. Development has already begun. The ULTRA lander is a model that integrates the APEX 1.0 lander originally developed in the United States with the Series 3 lander (provisional name) developed in Japan, combining the high quality required by customers with development efficiency.」
The plan was changed from independently scaling up the existing APEX 1.0 lander to developing the ULTRA lander, which integrates APEX 1.0 and Series 3. The design was also described as capable of carrying a maximum payload of 200 kg. - FY2026-H1AdvancedAnnual report
