The ASTOL-MB93 (93式メーサー攻撃機,   Kyūsanshiki Mēsā Kōgekiki, lit. Type 93 Maser Attack Aircraft) is a Maser-equipped fighter jet that appears in the 1992 Godzilla film, Godzilla vs. Mothra.


The ASTOL-MB93 is referred to in Japanese as the Type 93 Maser Attack Aircraft (93式メーサー攻撃機,   Kyūsanshiki Mēsā Kōgekiki)[1]:58—"93" referencing the year of its completion, 1993—or simply Maser Attack Aircraft (メーサー攻撃機,   Mēsā Kōgekiki).[2][4] Toho's official English website also uses the name Maser Attack Aircraft Type-93,[5] while the ASTOL model possessed by G-Force is described by the full title ASTOL-MB93 Maser Attack Aircraft (ASTOL-MB93メーサー攻撃機,   Asutōru Emubī Mēsā Kōgekiki) in Godzilla vs. G-Force Superweapon Manual.[1]:102 The craft is nicknamed the Maser helicopter (メーサーヘリ,   Mēsā heri), despite behaving more like a jet.[4]

Its designation ASTOL-MB93 (ASTOL (アストール)-MB (エムビー)93,   Asutōru Emubī Kyūsan) is derived from STOL, standing for "short takeoff and landing." The MB portion stands for "maser beam," with the 93 again being a shortening of 1993.


The ASTOL-MB93 was jointly developed by Bill, Co. of the United States and Fuji Heavy Industries of Japan.[1]:58[4] Equipped with dual turbojet engines and the latest in Maser technology,[1]:58 the ASTOLs were employed by the Japanese Ground Self Defense Force, despite being aerial vehicles.[4] While it was originally believed impossible to fit a fighter jet with Maser cannons, the reduced power consumption of the newly developed Type 93 Masers allowed for the ASTOLs' success.[1]:58

Despite not appearing in another film after Godzilla vs. Mothra, numerous books including Godzilla vs. SpaceGodzilla Super Complete Works describe G-Force as possessing ASTOL-MB93s in their arsenal,[6][7] possibly featured in cut footage from Godzilla vs. SpaceGodzilla. The publication Godzilla vs. G-Force Superweapon Manual goes into further detail, describing the ASTOLs as the "primary forces" of G-Force's Air Force.[1]:102 While their firepower was inferior to that of G-Force's ground forces due to their comparatively more streamlined frame, the ASTOLs' aerial bombardment capabilities provided a significant advantage on the battlefield.[1]:102 A typical assault force consisted of twin ASTOLs.[1]:102


Heisei series

Godzilla vs. Mothra

The ASTOL-MB93s received their baptism of fire after Godzilla emerged from Mt. Fuji and advanced towards Yokohama. As soon as he finished demolishing JSDF ground forces attempting to drive him out to sea, two of the aircraft began their attack. While their rays held Godzilla at bay for a time, he soon shot down one with his atomic breath and continued his march.




Godzilla, King of the Monsters

Shortly after the defeat of Megalon and Neo Biollante, Godzilla appeared in Tokyo and began to rampage. Hideo Kaneko and his brother, Yosuke knew that something was wrong, and Yosuke ran off, much to Hideo's objections. Shortly afterwards, Yosuke returned piloting an ASTOL-MB93 owned by G-Team, and began firing on Godzilla to try and drive him back. After shooting at 'Godzilla' several times, some of the giant monster's skin on its head and upper right arm fell off, exposing metal underneath and foiling its disguise. After firing several blasts out of his hands, the giant machine shed its failed disguise, and revealed itself to be Mechagodzilla III.

Yosuke's ASTOL-MB93 was later deployed during the fight between Godzilla and Anguirus at the dinosaur expo festival, and fired its missiles at the two monsters. Godzilla managed to catch one of the two missiles launched from the ASTOL-MB93 and jammed it down Anguirus's throat. Anguirus attempted to escape, but the missile detonated, killing him instantly and destroying KIDS in the process.

Yosuke continued to use the ASTOL-MB93 throughout the rest of the manga; it was ultimately destroyed by King Godzilla in the penultimate chapter when Yosuke attempted to mobilize it against the chimeric kaiju.

Godzilla vs. Mothra





  • Though the ASTOL-MB93 is a fighter jet, it appears to be largely based on attack helicopters such as the Apache and Cobra.
  • The sound the ASTOL-MB93s make in flight resembles that of TIE fighters from Star Wars.


  1. The 2012 publication Toho Special Effects Movie Complete Works (p. 234) erroneously lists the ASTOL-MB93's length as 13.2 meters.
