Hi all. Please let me know if the following info about the Impala is correct.

Is this info I have correct?

1. Aermacchi MB-326KC (Impala Mk.2)

Description:
A single-seat light attack variant of the MB-326, the MB-326K with a further uprated 4,000 lbf (18 kN) thrust Viper engine and strengthened airframe

In 1974 Aermacchi delivered to South Africa seven MB-326Ks in component form, followed by 15 more sets in the following year for assembly by Atlas Aircraft Corporation. Atlas then continued to build the type under licence as the Impala Mk 2, producing a further 77 aircraft.

General Information:
Crew :One
First Flight : 22 August 1970
Country of Origin :Italy, but manufactured under license by Atlas Aircraft Corporation in South Africa
Role: Attack, strike
Period of Service: 1974 - 2005
Powerplant:
-Number Of Engines: One
-Powerplant type :Rolls Royce Viper Mk.540 turbojet
-Max Power Rating :1,547kg (3,410lb)
Dimensions:
-Length :10.67m (35ft 0.25in)
-Height : 3.72m (12ft 2in)
-Wingspan :10.85m (35ft 7in)
-Wing Area :19.35m2 (208.3 sq ft)
Weights:
-Empty Weight: 3 123kg, 6,885lb
-Max T/O Weight: 5 897kg, 13,000lb
Landing Gear:
-Type :Retractable tricycle type with a single wheel on each unit
Performance:
-Max Speed At Sea Level :415kt (770km/h; 478mph)
-Range: 1 665km, 1,035miles

Armament:
The Impala could carry up to 6 x 120 kg or 4 x 250 kg bombs. The main armament consisted of 68 mm SNEB rocket-launchers (four x 6 or two x 18), and two 30 mm autocannon (with 300 rounds). These cannons were the real bonus for the Impala Mk II, helping to give a superior performance compared to earlier two-seat versions. The latter could also carry a pair of 30 mm DEFA guns in under-wing pods.

Cockpit: Glass cockpit

Impala MK 1 and MK2 Avionics:

Most of the instrumentation were 'steamgauge' driven. Except for the ILS/VOR system fitted with atc transponder on the MK1. The MKII had a RWR system fitted ,tacan computer and a proper gunsight with weapons (bombing) computer. vhf/uhf radios had frequency hopping and coding. Full IFF with mode 1 2 3,3 c. The ADI and HSI were electronic with remote sensors and gyros.

Communication:

MK1 and MK2: Standard vhf/uhf radios which had freq hopping and coding.

Navigation:

There was no airspeed altitude or heading info in hud display, only for weaponary system. Navigation was done by the tacan system (tactical navigation computer) and compass system with timer.

Sights:
The Impala had a gyro stabilised gunsight in the front of the cockpit with a camera.
The camera was there to record kill shots.

The electronic warfare suite:

Only the Impala MK2 had a RWS.
The RWS system on board was called the CRWS. (Compact Radar Warning System)
Grinell Avitronics developed a Missile Launch Warning System and a Chaff/Flare dispensing system to warn the pilot against incoming missiles and to distract the missile by Chaff or Flares. Atlas was contracted to do the installation design and upgrading of the SAAF aircraft.

2. Aermacchi MB-326M (Impala MK1):

Description:

Conventional in appearance, the MB-326M had a single Bristol-Siddeley Viper turbojet engine in the 9 kN (2,000 lbf) thrust class, a low, straight wing, and the two seats in tandem.
South Africa's Atlas Aircraft locally assembled 150 MB-326M as the Impala Mk.I, starting in 1966.

We did not have 18 tube 68mm rocket launchers, only the F-2 Pod which was carried, had 6 tubes.
The Mk-2's also carried V-3B AAM, and in the latter part of the mid-90's we carried V-3C trainer missiles too.
Up to the mid-80's the Mk-5 'Special Tank' was carried on the Mk-2, it was a 'napalm' type of weapon.
The photo recce pod carried on both versions was fitted with Vinten F-95 cameras.
30mm gun pods, NO!! :shock: :shock: The 30mm guns were mounted on the fuselage.
The gun pods were fitted with a 12,7mm machine gun.

Hi Spice. Is this info about the armament correct?

Armament:
The Impala could carry up to 6 x 120 kg or 4 x 250 kg bombs. The Mk 2 can carry 6 x F2 rocket pods with 6 rockets each. The Mk-2's also carried V-3B AAM, and in the latter part of the mid-90's they carried V-3C trainer missiles too.
Up to the mid-80's the Mk-5 'Special Tank' was carried on the Mk-2, it was a 'napalm' type of weapon. The aircraft had two 30 mm autocannons (with 300 rounds). These cannons were the real bonus for the Impala Mk II, helping to give a superior performance compared to earlier two-seat versions. .50 guns could be carried under wings on station 3 and 4.

I thought the gun pods were used only on the Mk1 for training?
