Приветствую
>она не только транспортный умеет изображать )))))). Фото нет но знаю совершенно точно, что на ее базе в ВВС израиля есть штурмовик - броня, иК ловушки, блоки НУРС под крылом и три крупнокалиберныx пулеметныx установки с круговым обстрелом (две по бортам и одна в задней двери фюзеляжа).

Про броню ничего нет, а про все прочее вот что джейнс пишет
Armament
Optional 0.50 mm Browning machine gun pack on each side of fuselage, above a pylon for a pod containing six 82 mm rockets. Rearward-firing machine gun optional. Librascope gunsight.
IAI ARAVA
Type
Twin-turboprop STOL light transport aircraft.
Programme
Design of the Arava light STOL transport started 1966; the first of two flying prototypes made its initial flight 27 November 1969 and the second 8 May 1971.
The Arava was first certified as a civil aircraft by the FAA in April 1972. This version, designated IAI 101, did not go into production, but formed the basis for the initial production Arava 102 (civil) and 201 (military) transport versions.
More than 90 Aravas had been delivered by the end of 1987, most of these being military 201s with the majority of military and civil sales being to Latin America. In 1984, the Israeli Air Force began to replace its Douglas C-47s in the main transport and trainer roles with a mixture of Arava 201s and 202s. Duties include that of multi-engined trainer for transport pilots.
Versions
Arava 101B: Modified civil version with PT6A-36 engines and accommodation for 19 passengers or 2,393 kg (5,275 lb) of cargo. Improved cabin interior and enhanced performance at higher ambient temperatures. Certified by Israeli CAA and FAA under SFAR Pt 41C. Only known customer was Airspur of Los Angeles, which received four of a cargo version (marketed in USA as Cargo Commuter-liner) in 1982 to 1983.
Arava 102: Initial production civil version, based on 101; certified by Israel CAA to FAR Pt 23 (Normal category) and FAR Pt 135 (Annex A). Accommodation for 20 passengers in airline-standard four-abreast configuration, with toilet. Available also, in a VIP configuration for up to 12 passengers, as an all-cargo transport, as a medical clinic for flying doctor services, and in versions for mapping, mining research, rainmaking and bridge construction, as flying laboratories for agriculture and health ministries, and for supplying oil prospecting units.
Arava 201: Initial military transport version. Prototype first flew on 7 March 1972. Three lease-operated by Israeli Air Force in October 1973, others delivered 1984 to 1985. Standard equipment enables a wide variety of missions to be undertaken. Total of more than 70 sold, including some equipped for maritime surveillance duties, fitted with either an AD-9 modification to extend the range and detection capability of the standard search/weather radar, or a more advanced detection system. Available also in several electronic warfare configurations, with various pallet-mounted ELINT and ESM packages, ventral or fuselage-side дустбинь радоме, реарвард-фацинг сцаннерс моунтед он тхе фуселаге таилцоне, а 60 кВА АПУ фор аддитионал елецтрицал повер генератион, анд нумероус бладе анд вхип тыпе антеннас абове анд белов фуселаге, он топ оф таилбоомс, анд елсевхере.

Дифферс принципаллы ин беинг лонгер, анд хавинг а фуллы wet' wing containing approximately 726 kg (1,600 lb) more fuel, wingtip winglets, and a boundary layer fence just inboard of each tip. Powered by 559 kW (750 shp) PT6A-36 engines; single-point pressure refuelling system. The winglet modification (but not the increased fuel capacity) is available as a retrofit modification of existing Aravas. Several 202s operate in South America and deliveries to the Israeli Air Force have included some of this version.
Upgrades
IAI: Arava 202 wingtip retrofit. See Versions.
Israel: The Israel Defence Force (IDF) operates three IAI 201 Arava aircraft as sigint platforms. The aircraft were fitted with an Elta EL/L-8310 ELINT system and a COMINT system thought to be built around the Elta EL/K-1150 or EL/K-1250 interceptor receiver. The IDF also operates eight IAI Arava 202 Electronic Countermeasures (ECM) platforms. For full technical details see Jane's Airborne Electronic Mission Systems.
Salvadorean Air Force: By February 1996, the Salvadorean Air Force had rebuilt and overhauled one derelict Arava. They are expected to obtain funds to rebuild two more Aravas.
Thailand: Operates three IAI Arava 201 aircraft as SIGINT platforms similar to those in use by the Israel Defence Force (IDF) (see above).
Operators
Versions of the Arava are in service with the armed forces of the following countries: Bolivia (1); Cameroon (1); Colombia (1); Ecuador (5); Guatemala (7); Honduras (1); Israel (11); Mexico (5); Swaziland (2); Thailand (3); and Venezuela (9).
The following description applies to the Arava 201, except where otherwise indicated:
Design Features
Braced high-wing monoplane with single streamline section strut each side. Wing section NACA 63(215)A 417. Dihedral 1º30'. Incidence 0º27'. No sweepback. Endplate winglets of NASA (Whitcomb) profile standard on 202, optional for other models. Fixed incidence tailplane.
Flying Controls
Frise light-alloy ailerons. Electrically operated double-slotted light-alloy flaps. Scoop-type alloy spoilers, for lateral control, above wing at 71 per cent chord. Electrically actuated trim tab in port aileron. Geared tab and electrically actuated trim tab in elevator and geared trim tab in each rudder.
Structure
Wing has light-alloy two-spar torsion box structure. The fuselage is a conventional semi-monocoque light-alloy structure of stringers, frames and single-skin panels, of increased length on 202. The tail unit is a cantilever light-alloy structure, with twin fins and rudders, carried on twin booms extending rearward from engine nacelles. Tailbooms were built by IAI Technologies Division.
Landing Gear
