ES-30
Overview
A 30-seat clean-sheet hybrid-electric regional aircraft built around Heart's Reserve Hybrid architecture for short-haul routes. Heart is positioning the ES-30 around lower operating cost, lower noise, shorter-runway access, and zero-CO2 operations on short segments.
Heart unveiled the full-scale X1 demonstrator in 2024 and has shifted to an iterative X1/X2 development path with more in-house technology integration. X1 completed low-speed taxi testing at Plattsburgh in late May 2026, FAA special airworthiness certification on July 23, 2026, and its piloted maiden flight on August 12, 2026 - the largest battery-electric aircraft ever flown. The X2 prototype is intended to mature the hybrid-electric architecture. In parallel, Heart is building the first pre-production, type-conforming ES-30 at its pilot manufacturing plant in Los Angeles, with flight testing on that airframe targeted to begin in 2028 ahead of a revised 2031 certification and entry-into-service target.
