The designation you are referring to corresponds to the official Finnish military classification and shorthand notation for the 100 kg Tolfvan Malli 1938 aerial bomb.
Here is the breakdown of the Tolfvan m/38, its military code PMiSp 100, and the mechanical designation SPish 9m as they apply to the Finnish Air Force during World War II:
1. The Weapon: Tolfvan 100 kg m/38
The Tolfvan m/38 was an optimized 100 kg general-purpose/demolition bomb designed by Oy Tolfvan Ab. Following the deployment of their m/30 series and m/37 variants, the m/38 was engineered to refine the ballistic trajectory and maximize the structural destruction of fortified structures, communication hubs, and rail lines.
2. The Code: PMiSp 100
In the Finnish ammunition cataloging system, abbreviations were heavily utilized to quickly communicate a bomb's tactical purpose and weight class. PMiSp 100 breaks down as follows:
-
- P (Panssari / Armor or Hardened)
- Mi (Miina / Mine or Heavy Demolition Blast)
- Sp (Sirpale / Fragmentation)
- 100 (The 100 kg weight class)
A PMiSp designation indicates a combined demolition-fragmentation weapon (General Purpose). It possessed a thick enough steel casing to punch through semi-hardened barriers or shallow earthworks before detonating via its internal fuzes, while simultaneously generating a wide-radius shrapnel pattern to neutralize surrounding soft targets and personnel.
3. The Mechanism: SPish 9m
The notation SPish 9m refers specifically to the mechanical release, suspension lug, or tail assembly architecture tailored for Finnish and adapted foreign warplanes:
-
- SPish stands for the specialized Tolfvan safety-pin and release shackle interface designed to slide cleanly into heavy internal bomb bay rails.
- 9m designates the specialized 9-spoke tail stabilizer fin module (or 9-rakoinen vakainperä), which was introduced to eliminate aerodynamic wobble when dropping the heavy 100 kg ordnance from high-altitude bombing runs.
This complete kit allowed the Tolfvan m/38 to be loaded seamlessly into the belly of the Finnish Air Force's primary medium bombers, ensuring stable flight metrics and reliable fuse timing upon impact.
