Marinha Portuguesa / Re: Substituição das Fragatas Classe Vasco da Gama
« Última mensagem por Duarte em Janeiro 17, 2026, 08:10:40 pm »Por acaso estou um bocadinho preocupado relativamente à configuração das nossas EVO.
Passo a explicar.
Li num fórum italiano que a configuração proposta a Portugal teria, supostamente, um canhão de 127 à proa.
Isso, também supostamente, implica prescindir das segundas 16 VLS, por uma questão de espaço necessário ao módulo de 127mm.
Se somarmos a isso a configuração inicial italiana, que seria com 16 VLS, e o facto dos primeiros navios afinal transitarem para a MP... pois...
Mas por outro lado a minha esperança aumentou quando o Subsea7 acenou com a possibilidade de outros voos no que respeita a mísseis, por isso é esperar e continuar a contar os dias.
Acho que não é este o caso com as EVO. Talvez com as FREMM originais?

What could reduce VLS on an export ship
If a Portuguese (or other export) FREMM EVO ended up with fewer than 32 cells, it would almost certainly be due to:
Cost / budget choices
Weapon policy (e.g. no cruise missiles → no need for A70)
National combat-system preferences
Growth margin decisions, not physical incompatibility
But a 127 mm gun does not force that outcome.
Bottom line
✔ 127 mm gun + 32 VLS is a fully compatible, already-designed configuration on FREMM EVO.
If Portugal receives the two Italian-built hulls largely “as designed,” there is no technical reason they couldn’t retain both.

No — **the 127 mm gun does *not* preclude the 32‑cell VLS** on the FREMM EVO. In fact, the Italian FREMMs (the baseline for Portugal’s ships) already combine **both** systems without any spatial or structural conflict.
## Why the 127 mm + 32 VLS combination works
### 🔧 Deck layout is designed for both
The FREMM EVO inherits the same forward architecture as the Italian FREMM GP variant:
- **127/64 LW gun forward**
- **32 Sylver A50/A70 cells directly behind it**
- **Radar mast and superstructure further aft**
This arrangement is already proven on multiple FREMM hulls. There is no interference in terms of weight, recoil, or deck penetration.
### 📐 FREMM EVO has *more* internal volume, not less
The EVO adds:
- A redesigned bow
- A larger mission bay
- Updated superstructure geometry
None of these changes reduce the forward VLS footprint. If anything, the EVO has *more* margin for future systems.
### 🛠 The only FREMM variant that *reduces* VLS is the French ASW version
And that’s because France chose a **76 mm gun**, not because the 127 mm gun forces a reduction.
Italy’s FREMM GP ships — with the 127 mm — always kept the full 32 cells.
### 🇵🇹 For Portugal specifically
Since Portugal is negotiating for the **Italian-built EVO hulls already under construction**, the configuration is:
- **127/64 LW gun**
- **32 Sylver A50/A70 VLS**
- **No redesign required**
Changing either the gun or the VLS block would require a structural redesign that Portugal would not pay for.

## Quick comparison of configurations
| Variant | Main Gun | VLS Cells |
|--------|----------|-----------|
| **Italian FREMM GP** | **127/64 LW** | **32 Sylver A50/A70** |
| **FREMM EVO (Italian baseline)** | **127/64 LW** | **32 Sylver A50/A70** |
| **Likely Portuguese FREMM EVO** | **127/64 LW** | **32 Sylver A50/A70** |
